peanut butter/epoxys

[Lamberdinghy170]

Whats is peanut butter exactly and what are the best epoxys to use for holes. During our restoration we accidentally put a 2 inch slit with an angle grinder into the hole while removing the deck and foam. We also need to fill holes in the hull from a previous depth finder. We have a 92 sea ray 170 we are doing a complete restore on as everything hull up was rotten and watterlogged for the most part but surpisingly motor needs minimal work and runs. Our first boat we have lots of questions and need lots of advice.

Get a photobucket acct (free) & post some pix of what you're working on.

Decide if you want to use epoxy or polyester resin. Pros & cons for both. Filler (PB~peanut butter) can be made w/ either epoxy or poly resin, and in several different mixes depending on exactly what you're filling & how it'll need to perform once cured. Filler for a few slightly larger then a pin hole in fresh gelcoat will be made 1 way (thin), large nicks & dings another (actual creamy PB consistency), and if you want to attempt to fill in the existing bilge drain tube hole & redrill it slightly lower, still another way (hairy PB, fairly thick & made w/ fine chopped strand fiberglass pieces added).

So, epoxy or poly resin?

From the resto forum homepage, do an advanced search for epoxy VS poly. You should get lots of hits, fairly frequent topic of discussion. LOTS of opinions to support either choice. And you can do the same for peanut butter. Friscoboater calls his fillers 'Pookie' and has great info in his threads as well as youtube videos & a boat building blog site. Oops has a hull extension thread that has a great index at the front for finding info in his threads. Oops & Friscoboater threads may both be found here:
@Don's helpful How To's and Other Great Information

What all are you planning to do to the exterior of the hole beyond filling a few holes from the previous owner & adding a slot of your own. It happens, to most, many more then admit it I'm sure........

BTW: the iboats server posts 5 similar threads at the bottom of every thread, here's 4 of the 5 at the bottom of yours:

Re: peanut butter/epoxys

Hi thanks for the links, i'll def check them out. i'm really not sure what we are planning to do to the outside only because i'm not sure what we are 'supposed' to do. Is a fill just enough, or are we to fill then re glass and re gel etc....seriously, we're like a kid with peas and a spoon here all I know is holes and boats don't mix! And yes frisco's youtube video's have been our lifeline so far, thats actually what got us into this mess haha, hubby forgot to take into account that his boat was much larger than ours when grinding so didn't think he'd run into the hull so quickly...lesson learned! I'm trying to upload some pics but it says my html is turned off and couldn't see a way to turn it on so i'm not sure if this will work, in my old forum we just had a tab to post it under and it came right up so....here it goes......oh and any history buffs? Seriously we can find NOTHING on a 1992 sea ray 170 on sea rays website, no spec sheets no nothing. closest thing i've found is an owners manual for a 1993?? is it the same as another model that we should be looking at? Our goal is to tear it all out basically put back down the two main stringers, somehow, we're not even sure how we're supposed to keep them standing, and get a floor back down, we have determined this is the second floor thats been put in. It has been sitting in the weather for about 5 years and used twice. Before that the guy who had it put a new floor in by screwing plywood into fiberglass and foam everywhere no sealant or anything was used. So naturally combined with sitting in the weather water got into every hole and foam and it just rotted despite feeling hard as a rock when we got it. The only reason we tore up the floor was because we knew sitting that long it had to be rotten. When removing the drivers side foam, the trailer tire lost the huge bubble it had in it from weight.

Re: peanut butter/epoxys

It looks like you have cut away a portion of your port stringer already. To replace them you will need to know there shape. Try to keep the starboard stringer intact if you can, so you have a template.

How is the transom? I see you haven't removed the motor yet.

Re: peanut butter/epoxys

Welcome to iBoats!

If you haven't already done so take a LOT of detailed measurements across the deck, and top to bottom. Stringers, top to bottom EVERYTHING. You'll need em later. The first link in my Signature line below will be helpful along with this pdf attachment...

Re: peanut butter/epoxys

you can of course make your own thickened epoxy or buy pre thickened epoxy. Note that it takes about 2 quarts of thicken/filler added to one quart of mixed epoxy to make just about 1.1 quart of thick epoxy. So, it is often cheaper and easier to purchase pre thickened epoxy.

Wet Dry 700 epoxy paste is thickened with kevlar (tm) and feldspar - about $100 a gallon. It can be applied underwater and used with or without fiberglass cloth. It has saved a lot of leaking swimming pools, leaking floating homes and damaged boats. Often finds itself on-board boats heading off-shore/around the world...

Re: peanut butter/epoxys

What is the best place price wise to order from. Im thinking of taking the epoxy route vs poly as from reading it appears to be stronger and a bit more durable. I was looking at us composites last nights but was wondering if there is another place out there cheaper. Yes there will def be lots of measuring going on. We cant save either stringer...both are completely rotted throughI can pull them out with my hand. Ill up load closer pics tonight. Transom we arent sure yet but we are going to check. Just trying to get someone with a crane to help us out and see if we can get our hands on an engine hoist or picker. It does appear to be fiberglassed in well....but the open depth finder holes were drilled right into it so im not holding out much hope

Re: peanut butter/epoxys

You can use epoxy, but your boat is made entirely from Poly and Poly will do the job just fine and last for decades. Epoxy takes a lot more "BabySitting" and cure time so it's a slower process. USC is about as cheap and good as they come unless you find it locally. Not sure where you are so... can't guide you on that.

Re: peanut butter/epoxys

US Composites epoxy is not a long cure. The fast is 1-2 hours set and 3-4 hours cure. Medium (what I use) is set time 3-4 hours and cure 8-10.

USC says their poly resin is 1-2 hours gel, and overnight cure.

Poly carries a $25 hazmat shipping fee, and only lasts 3 months on the shelf.

Re: peanut butter/epoxys

USC makes a Slow Cure Epoxy too!

Re: peanut butter/epoxys

...for folks who move really, really slowly, or live near the equator. I'm not sure who would use it.

 

[Woodonglass]

Re: peanut butter/epoxys

When temps are in the 90's or 100's it will cure just like the medium cure stuff. If temps are below 80...well it's gunna take a long time. It's all about Temperature. Here in Okla, and down in Texas we can use it in the middle of summer and still have to Hurry sometimes.

Re: peanut butter/epoxys

I thought the slow cure in high temps was so you dont get glued to the boat when you pass out

Not many things i want to do in 100 degrees, except maybe surf...

Re: peanut butter/epoxys

Ok we're in Va about an hour from va beach and right now temps are 86-100 degrees with high humidity so epoxy should be a no go? I'm really just worried about mucking up the mixing of the resin, we don't have unlimited funds so it will likely be a slow process we were hoping to kind of pay as you go sort of deal since we got the whole boat and trailer for 300 bucks. YAY we finally own something outright free and clear!!! even though we don't technically have a title or anything because they just moved and its still packed away. Friends of ours so we trust them but the darn DMV and wildlife fisheries people are the one's who scare me...yikes. Anyway got those photos of what used to be the stringers...here ya go...






this is why we've been trying our damndest to get a spec sheet.....measurements wise, its gonna be a close guesstimate....

Re: peanut butter/epoxys

Don't get to worried about it. It's not brain surgery. It'll come back together easier than you realize. We'll be here to help all along the way.

Re: peanut butter/epoxys

What do you all suppose the possibility is for just tying into the stringers somewhere under the console area are?Is Iit possible or not even worth trying coconsidering the rot we have. They dont go up much further but it would save so much time if we disbt have to rebuild the consoles and 3 bench seats up front? Is there any way to tell before tear out or are better off just starting from scratch?

I doubt you need to rebuild the consoles. Just dig out the stringers and decking under them and the consoles will hang in the air waiting for the new deck, as they are really part of the cap.

Here is the bottom of my consoles right now....sitting on nothing. I can run my hand between my new stringers and the bottom of each console.
