can anyone tell me what to do to get rid of stress cracks and spider web crack so they dont come back in the new paint

[Racemore]

You should search the Fiberglass forum but the short of it is the stress cracks are from flex and if you don't stop the flex it they will come back.
The repair process is also a factor.
They have to be ground out and filled completely before the finish coating is done. Sometime bottom or backside reinforcement is necessary to prevent excessive flex. Flex agent additives help and superior resin like vinylester.:cool:

I thought Racemore did a nice job of replying. He pretty much summed it up.

You gotta remember something here before you gripe...it's the weekend and most guys here are out running their boats, so answers will be a little slow. If you want a right answer, be patient, the last thing you want is a bunch of wrong replies. A post in the lounge on a subject that everyone has an opinion on will draw a lot of replies, a post in a subject only a few are qualified to answer correctly will take some time.

The stress cracks on the bottom are probably from the bad floor you had before. if everything was done right when the floor was replaced, you should be good to go and just grind out the cracks and fill them like Racemore said.

Use the "Search" up above. There is nothing you CAN'T find by searching. That way you won't get ripped a new one when asking a question that has been beat to death before. I posted some stuff, vids, that I found on youtube. The answers are all over the place.

give people time to see the post and the replys will come......benji

[stylishskier]

you mentioned new transom and floor? what about core??? Core could be the cause of all those stress cracks, if it hasn't been replaced right, its probably pulp by now...

[OneBadVector]

i did the core when i did the floor gettin ready to paint and doin the transom before i get it paint so it will all good for a long time i didnt use wood in the floor or the core i used composite and goin to use it in the transom to thanks for the help

[flabum1017]

I would'nt use composite in the transom..... just good old marine plywood.

IMO

There is more to fixing glass than grinding and filling. First, why did the cracks occur? Most likely the bad coring in the hull, and a weak transom created flex in the boat. Fix this and you have a good start. Grinding the bottom of the hull affects the running surface. Not getting it back, exactly, to where it s supposed to be, can make the boat un-handleable. Before you take a grinder to the boat, read the fiberglass threads, maybe go to the library and read a book or two about boat repair. Knowlege is the power. Then decide if you want to put the time effort and money out to make the repairs. Even if you decide to have it done, you should understand what you are paying your money to get done.
