Resurrecting the Demon

[din_blix]

This is my '84 cajun demon II, all taken apart and ready for rebuild. The floor as you can see is totally boned and the stringers and transom will need attention also. The deck has some rot around the live wells and at the very front where the trolling motor was mounted.

Re: Resurrecting the Demon

I posted these pictures at like 10pm last night and my brain wasnt working very well, I do have questions about which fiber mat/resin i should use. I see the west/uscomposites recommended here alot but is it really necessary to use these marine specific types? Would 'good ole' bondo brand fiber mat and resin work? Or would I just be setting my self up for a repeat or this rebuild.

Re: Resurrecting the Demon

start reading on the forums bud.
you got some studying to do, and this is boat university.

there are 3 basic types of resin used in boat building

1.polyester resin. either waxed or un waxed

2.vynal ester resin. or VE reisn for short.

3 epoxy resin

poly is the lowest grade of resin between the three but far stronger than you will ever need in a boat, your boat is made from poly. it is the industry standard for boat building, and everything from fiberglassing car speakers to countertops and showerstalls

"good ol bondo" resin is poly resin but it is waxed.

2 VE resin is stronger than poly and newer boat hulls are made from it

3 epoxy....known as "the glue" very good resin, but will be waay over kill for what you need 2x as expencive as standard poly

the standard used here at i boats for material with poly is chopped strand matt or csm.
the standard cloth used is a 1708 bi ax it has both chopped strand matt and a woven cloth mixed in one material. it is very strong

hope that helps

cheers

Re: Resurrecting the Demon

Im leaning towards the bondo 'boatyard' resin mainly because of cost, not sure if should get 1.5oz csm or 3/4 oz.

I did some cutting on her yesterday after work, I wanted to get the old floor totally out but this is as far as I got before the heat got to me.

Hello Blix..

You should not use Bondo resin... It will kick faster than you can work m8..

cheaper is not better unless your only filling small cracks..

Trust me..
