Hello ALL,

Some of you know I'm in the process of rehabbing/repowering a 25 T Jason.

When the time comes I'd like to "cleanup" the hauling side of the boat.

The original owner had the side painted blue.

When I had the bottom glass bead blasted I had the blue blasted off the side.

What do you guys suggest I do to "cleanup" the side a bit. At the least I'd like it "all gel coat white" and a little smoother. After the bead blasting there is quite a bit of fiberglass hairs sticking through.

I don't expect to get it "out-of-the-mold" smooth..just "clean looking".

Any suggestions on the process ????

On the right side of the pic you'll see some pink poly/fair.

I had 3-4 oz in a can and as a quick "experiment" I mixed it up and troweled some on the mat. Tomorrow 'll sand it down and "see what happens" .

Appreciated, Bill D

I would lay a few layers of mat up on the hauling side so it could serve as future chaffe gear and then just gelcoat it white or paint it a different color all together.

In the past I have always just brushed or rolled on a thin coat of laminating resin to harden up and seal the rough exposed fibers.

Then use some of your pink poly/fair or what ever fairing compound you want. Use a long sanding block to fair in.

Mike,
You can't really see in the picture but the chafed hull is 1/2-5/8 inch thick over the original gel coat already. The hull side will not get beat up @ all with me hauling 10 traps with no trawls.

I hadn't thought of that....good idea.

I was thinking of maybe grinding it ALL off down to almost the original gel coat, fairing re-gel coating the area and try to get it back to "almost new".

A project like that would be "next winter". I have my hands full getting the boat ready for June 1st

The hard part there is the gelcoat work, no? Grinding and sanding might just be a couple hours. No plans to paint the topsides all around I guess? Just figured you would be painting that thing all over.

I orbital sanded a few areas around the hull with 220 and then wet sanded with 800-1000.

It is remarkable how the gel coat has come back to life. She'll come back all nice and shiny without paint.

it may be hard to color match the side to do the repair, you may have to do the entire side of the boat to make it look new.

how about adding a stainless plate to that area. or a different color , it would look normal then as a chafe spot for pots.
