Is there anything I can use directly on the mold as a release without having gel coat, sand and wax? What about oil on the osb? Any negative effects? I may do a test piece and see if it bonds to osb wiped down with oil. Also thinking about some kind of paint that poly resin wouldn't bond to.

If I can get one good layer on it then the rest would be easy to build any thickness that I want.

PVA should do what you want. I'd do it on a test piece before jumping in with both feet.

A couple rolls of heavy clear packing tape from office supply and a couple hours time and you will be back in business. A coat of butchers wax or pva if you like and glass it up. No reason to change direction, just technique.

Surv,
I would use spray adhesive and glue aluminum foil all over that mold you made. You could wax it or PVA but I wouldn't bother.You might have some foil stick to the laminate when you pop it off but that easily pulls off.

You have to have a solid substrate to glass too no matter what your doing or your beating a dead horse.

Don't give up on what you have, your on the right track.

After testing a few different methods I found that turtle wax was the easiest to apply and of my samples it released the easiest. I masked all the corners and seams then used a paint brush and painted the mold with two coats of turtle way.

Today I got about half of it covered with fiberglass. Two layers of 12 oz. uni glass oriented 0/90 and a layer of 1.5 oz chop strand mat. It should be close to 1/8" thick maybe just a hair shy, ill measure a test piece after it kicks. Lay up is kind of slow going, I spent about 7-8 hours on it today. I thought I would have the whole thing covered but its coming along.

Keri with it, always a struggle to step back and try another direction. Looks like you got it this time.

The stringers are getting close to being finished. I need to finish up a little on the two bulkheads in the center. I wet out a lot of glass the last two days, weathers good for it. Right now here's what's on them,
12 oz uni 0
12 oz uni 90
1.5 oz mat
12 oz uni 0
12 oz uni 90
24 oz woven roving
1.5 oz mat

I haven't measured how thick they are but they are getting thick, its getting hard to see the masking tape through the fiberglass. I would guess 1/4" or a little more.

On another subject, I need to decide if I have to replace the transom or not. I stripped all the hardware off the transom getting ready to replace it but all the screws were in solid wood. It also sounds the same when I hit it with a rubber mallot. Is there any sure way of testing it to see what condition the wood is in? I know if I replace it its going to be a job getting this transom out.

About the only way to be 100% sure on the transom condition is to drill test holes and see what the shavings look like.

I drilled some test holes. A few were dry, a few were wet, nothing rotten. Its probably wet because i didnt seal it up after removing the bracket, I assumed it was rotten because of how rotten the stringers were. They did a good job at the factory of sealing the transom and filled the holes around the scuppers with some kind of thickened resin.

Peel ply would have been perfect for what you are trying to do. Maybe next time

Looking real good surv, professional work! With all those layers of glass and so many different surfaces on that stringer grid one can certainly see it takes time to do it right.

On the transom...... I tend to suffer from "might as well" syndrome. Once I pull the deck I prefer to replace everything. For some reason I want it all new and don't want any old work or wood left behind. Plus if you ever sell it any potential buyer will ask if transom was replaced........ But I know I have issues....LOL
