The Kool O Matic is coming off today. Reading Jerry Whitaker's post on the screw holes seems like a lot of work. Is there something in a tube or bottle that would fill the holes with a product similar to gelcoat? I will check at the boat store later for suggestions from them.
I fill screw holes with Fiber Teck epoxy and 406 powder and I make it thick almost
like putty.
Marinetex
I removed old antennas, cable guides, a patch plate,luggage rack, and filled 111 holes!
I used fiberglass body filler with good results. No doubt the other products would be as good or better.
For a quick and easy, I would use polyurethane caulk from HD or Lowe's.
On my last rig I broke up a bunch of toothpicks, rolled them in glue, and then shoved them in the hole and trimmed them to be flush with the wood portion of the roof. Then applied the sealant (epoxy of some sort in your case?) over the top
Just got off the phone with the boat shop. Quarts is the smallest quantity of gelcoat he sells. Suggested 5200 for my issue. There are 50 # 6 screw holes to fill, cosmetics don't matter to me on the roof. I will taper drill to get an area that whatever I use can penetrate. I have bought Bondo in tubes before from auto stores but never used it for this purpose.
Adhesive caulks come in tubes and work very well
I've used PC11 on my boat with excellent results. Also used it on my Foretravel roof with good results. Two part epoxy rated for below water line use after cured. Can be purchased at many hardware stores. I use two plastic spoons to place it onto mixing surface, then throw them away, blend with putty knife and apply. Also available at Auntie Amazon. PC10 cures a much darker shade. It is drill able.
I've also used 5200.
To make any patch easier to make "clean", after surface is completely clean get some 2" blue painter's tape. Use a hole punch to make holes and place the holes in the tape over the roof holes. Fill with a caulk OR Marinetex (my recommendation). Just before it hardens, remove the tape if caulk.
If patching with epoxy, Marinetex, etc, leave the tape on until cured. That will leave the patch just slightly proud of the surface (by thickness of the tape). Sand with tape still in place until all the tape is exposed, leaving the patch neat and round. If really picky, after removing the tape, sand flush with the roof.
Thanks for the info PC-11 will be here Thu. will use the blue tape suggestion.
As mentioned above, I'd use 3M 5200 fast cure. That is wicked stuff. I've used it in the marine environment, for underwater locations and it's tough stuff.
When I removed the old satellite dish, I used Plastic Aide. It is good stuff. Mix in a little cup, them pour into the hole. You can sand and paint if preferred. It is an off white color. Works good on any plastic, fiberglass, pvc, etc.

I find 5200 very difficult to work with. So sticky that it is hard to smooth out.
