Need help with bottom job

[juicyhook]

This year I decided to get rid of that ugly and old bottom paint. During the

process the guys I had sanding the bottom went throught the gel in a few spots. So now I am wondering if I should get some gel and brush some over the spot to seal them up before starting the refinish process.



I am going to be applying the petit vivid 3 part system. Scrubing the bottom with red scotch brite and bioclean. One coat of skip sand and 3 coats of petit vivid white. The boat is going to stay in the water for 5 months and on the trailer for the remainder of the year, with a few haul out to pressure wash the bottom.



So really I am worried about water seaping through the petit causing blistering. Really the barrier coat process is something I am tring to avoid

due to the fact that I may strip it again one day if it ends up on a lift. The guys said stripping the barrier coat will be next to impossible.



So do I leave the few spots exsposed and let the bottom paint and primer do the trick or do I spray or brush on a few coats of gel. Its been sanded

front to rear with 80 grit. There are 7 spots, 4 are quarter size and the other are lines shaped lke pencils but shorter.



Thanks for the advice.

If they broke through the gel coat in many, the right way is to apply barrier coat - multiple layers to build up a solid protective coating that is water proof. If it is just a few spots, you can feather out the edges of the gouge and fill with epoxy before applying bottom paint.

There not really gouges, if you run your hand over the area and had youe eyes close you would never know it.

Just looking at it you can see a hint of brown.

Will the epoxy be ok just coating a few spots, as far as creating a solid bond to the area. I would hate to see me create a spot for the bottom paint to fail cause I did not
do the entire bottom.

I have used a two part epoxy paint to do what you are talking about. Not Awlgrip but a heavy industial type that is thicker. Most paint stores carry it, Sherwin Williams etc.

A lot of the boat builders use it for painting the bildges in boats and for a primer on under deck parts.

I think this will work fine for what you are trying to accomplish.

Good luck,
Troy
