Re: FIBERGLASS a "BIG HOLE" --1973 MFG Super Caprice

My best advice is this. Make sure that all your surfaces are prepped really well. Grind down to fresh clean glass. Wipe all of em down with acetone and get rid of all contaminates. If the new glass has a clean surface to adhere too, your repair should go well. The materials listed should be all you will need. As YD says you don't HAVE to remove the Top cap but working upside down for a Newb will be a challenge but... It can be done, and we will be here to help you with the process.

Re: FIBERGLASS a "BIG HOLE" --1973 MFG Super Caprice

Things I have listed that I need to obtain for this project---- What is not needed and what is missing?
1) full/Half Face Repirator mask
2)2 pair Chemical Gloves & box latex
3)Sand Paper
-40 Grit to start
-80-100 Grit between layers
-up to 220 Grit painted surface
-gel Coat 2000 Grit
4)See through mixing cups 1quart in size
5)Resin Brushes different sizes
6)Masking Tape
7)Acetone
8)Plastic wrap
9)Gel Coat to match hull paint---or----PAINT if it is cheaper and easier
10)Fiber Glass rubbing compound---
11)Laminate rollers
12)West System 105A Resin – Quart
or POLY RESIN
13)West System 205-B Hardener - .86 Quart
14)West 407 is a micro balloons filler and
15)406 is silica for thickening
16)Fiber Glass Cloth/1708 Biax
17)Mat/fiberglass
18)Talcum Powder (babypowder)
19)Glass MicroBubbles
20)Cabosil

#9 I was thinking of painting it black accross the front of the windshield about 12inch or so to cover the fixed spot and look like thick stripe going accross the boat--- So do i need the GEL coat if I plan to paint? What kind of Paint base>?

#10 FiberGlass rubbing compund would only be needed if I was going to buff out my boat correct?

#12 What is a good Poly Resin or should I buy 105A resin from WEST>

#13 No one mentioned to use a Hardener but i came with a WESTSYTEMS kit I purchased last year

#14 & 15 I need ratio of RESIN to MicroBubbles or ratio of Silica to Resin for the filler

#17 the MAT fiberglass was suggested I put between the new glass

#20 Cabosil is the same as Talcum Powder or Silica>?

I need STEP by STEP instructions for this as I'm new and anal about getting directions before I do anything


1st I tape off the Outside and start on the inside. RESIN then lay GLASS, then RESIN, the let dry. Sand then more RESIN then more GLASS then RESIN, then let dry, Repeat a few more times as needed
2nd remove the outside backing and RESIN, put in the MAT as suggested, then RESIN then lay some GLASS, RESIN let dry. Sand and repat as desired thickness is achived

Asumming I do that correctly then I would be ready to make Fairing? How do I make it> what ratio of Talcu/Silica/Microbubles to RESIN should i use?

once Fairing is made...Fillin the outside, make smooth with a putty knife. and let dry...sand then is it ready to paint?

Looking for details on the acutal procedure....tyring to take bits and pieces of information from all over and make an iteniary

First off Where are you located? This will help us to help you find the closest location for you to purchase your materials. You need to decide what you are going to use. Epoxy or Poly. I'd recommend Poly. I'd also recommend Paint for the finish. Once you tell us what you are going to use for sure then we can narrow down your purchase list to help ensure you only order what you'll need, and get the most bang for your buck.

Pittsburgh, Beaver County,---I may have posted that list ALOT premature. I found the Fiberglass Forum (all defintions and descriptions of the JOB) on here for beginners and have copy and pasted the whole section in a Word Doc. and printed-- http://forums.iboats.com/boat-resto...e-fiberglass-information-thread-286013.html--

I will study and then decide... So far it states Epoxy is for biginners simply b/c it is a little more flexiable but does stress it doesn't matter if sanding and prepping is done properly.

also PAINT is my choice just as simple as stated. This year is fixing the HOLE and Tuning the engine plus some electrical like tach and lights....next year maybe cosmetic.

Fiber Glass work
-Half/FULL Face Repirator mask
-2 pair Chemical Gloves & box latex
-High Speed buffer with LOW setting
-Sand Paper
-40 Grit to start
-80-100 Grit between layers
-up to 220 Grit painted surface
-gel Coat 2000 Grit
-See through mixing cups 1quart in size
-Resin Brushes different sizes
-Masking Tape
-Acetone
-Plastic wrap
-Black Paint ?RUSTOLEUM ENAMEL-
-Fiber Glass rubbing compound
-Laminate rollers
-Foam tip brush

-Poly Resin ? gallon
-West System 205-B Hardener - .86 Quart
-Fiber Glass Cloth/1708 Biax
There is a product available called ?combination mat? or Biaxial mat . It is a ?combination? of woven roving , and chopped strand mat. They are stitched together. It is sold in various weights. It is also called stitch bonded mat
-Mat/fiberglass
Chopped Strand Mat 1.5 ox-between layers of Biax
-1/4" Chopped Strand
This material consists of 1/4" chopped fiberglass. Used to increase strength especially in tight corners.
- (Babypowder)
rub on before beginning project--
-Cabosil/ Silica
Thickening agent for epoxies, polyesters, and urethanes. Thicken resins to your own taste by adding varying amounts. Ideal for making adhesives and putties for gluing wood, fiberglass, stone, concrete, etc
-West 407 is a Microballoons filler
-Phenolic Microballons (BJO-0930)
These red/purple color Phenolic spheres when mixed with epoxy resins will create a low density paste compound which will sand easily and improve strength/flexibility of the cured resin. Better for large gap filling
-3M Glass Bubbles-
These hollow glass microspheres can be added to any epoxy and polyester resin. These bubbles will make a lightweight, easy sanding putty for minor surface filling of cracks, holes, etc



This will most likely be my list

Get the windshield off and just start chasing bad glass with a 4.5" grinder with some 24g.

If your unsure if you need to grind more then help us out with some pics :)

You dont need the epoxy stuff.

You dont need the heavy duty dishwashing gloves ( a box of Powdered latex gloves should do fine ).

Your going to need a 1/4" die grinder with a good abrasive nose bit.

A 1/8" cut-off wheel might help.

You can just pour your baby powder into your suit arms and legs .. Not really gonna do you much good to rub it into your body as you need to sweat. You can shower with thick and foamy shaving cream and a Luffa Pad after your grinding to help ( I find this not needed after buckling up with a good suit ). Oh yea .. nobody ever said you have to wear just ONE suit at a time ;) .. I have Double suited up before when Crawling into those glassy grindy areas were its just a friggen dust storm.

Heavy duty wet dry vac on hand. Turn it on and put the hose as close as possible to your grinding. Yes it does help especially when in confined areas.

Also another thing that you did not list is a good pair of EAR MUFFS. Please do this as part of your safety program :D

I plan on purchasing most items online. If I can find it all local and at a price that beats online then I would do that but my expierence is online can be cheaper. the Gell coat 2000 grit would be the grit suggested for sanding the gel coat which I don't think I need.

------
thx for the advice on grinding and sanding more...I know I have more to do all in due time. And the tips for working in confined spaces... ear muffs and shop vac and how to handle fiberglass irritation,

___
back to the procedure of it all
1) continue grinding inside and out
2) I would clean with acetone let dry
3) tape off and mold the outside
4) Mix resin with MEKP and Cabosil/Silica? stuck on how to mix correctly
5) Lay up 1708 biaxial mat and resin again and smooth out bubbles
6) let dry and sand then repeat.


Is that pretty much the procedure? and elaborate on the Resin, MEKP and Cabosi/Silica mixture in LAY MAN turns please.

Re: FIBERGLASS a "BIG HOLE" --1973 MFG Super Caprice

I meant to say lay up the biaxial fiber on the inside first a few layers, then I would move to the outside remove the taped mold. then insert the chopped strand mat 1.5oz and resin then lay the 1708 biaxial again resin... sand repeat... is this the right track?
also once the inside and outside base was done then was going to add 1/4" chopped strand in the tight corners on the insde.....

then was going to ask how to make the good fairing filler with Phenolic Microballons ? or the best way to make fairing filler....

Need opions on how others mix the resin with the various products to do different things.

Re: FIBERGLASS a "BIG HOLE" --1973 MFG Super Caprice

Question for the panel...could one tape the area creating a mold base of sorts then spray it with a foam product. Once dried, remove the tape and glass the mold you have made; or leave the foam mold for support encased in glass. This "method" is used often in custom car building and other hobbies so, although a process, should work.

Let me get you correct.... duck tape the outside very carefully and to make a nice layered mold....then spray the inside of the hole with foam filler....let dry.... then take the duck tape off on the outside....sand a little...then lay the glass.....multipy pataches in all the cracked angles, then a few whole pieces to cover all the multipy patches of glass. let dry.... then probaby remove the inside spary foam and sand a little.. then lay a few big pieces of biaxial 1708....then finish it up .... is that the process your decribing? if so it doesn't sound like a bad idea at all to me....any opinions?

Re: FIBERGLASS a "BIG HOLE" --1973 MFG Super Caprice

Exactly (almost). :) I would use paper tape like a painters tape or that tan paper tape. Duct tape is too sticky for me. Spray in the foam and it should create a positive mold to fiberglass.

Composite Mold Making

Here is a process on youtube that should give you an idea of what I mean. They used newspaper, but tape would hold your shape better since it's a small area.

Good luck!

In your case I would feather the outside and layup the outside first. Form on the inside. Most of the grinding will be on the outside. Your going to be finishing the outside anyways .. no reason to grind the inside anymore than you have to :) Duct tape and stir sticks should do you fine.

You can always goto the inside and lam more. But at least its flat ;) .

I,m guessing . Because I,ve never had to do a repair like this . Just an idea . Use the the stir sticks but place a piece of cardboard with packing tape on it bent to fit the shape then lay up the glass on the outside as YD suggested . Secure the mold from the inside with whatever means necessary. I guess once the glass is built up the right thickness sanded and faired all will be good . :)
