Can somebody recommend what product is best for filling smaller screw holes. I am most familiar with west systems epoxy. Or if there is a better product/technique??

You could use West System epoxy. If you do you will have to gelcoat, paint or cover the repair with a fitting because the epoxy will deteriorate in sunlight. For holes in a vertical side you'll have to be ready to slap a piece of masking tape over the repair to keep the epoxy from running out. You could mix colloidal silica into the epoxy to thicken it up but wear a mask because you really don't want to inhale any of the silica which will seem to blow around when there is no breeze. You could use MarineTex. You can get epoxy syringes for a dollar or two each where they sexy a West System epoxy which make injecting the epoxy into holes easier. I don't think MarineTex deteriorates in sunlight like epoxy but it's thick so you would probably use a plastic putty knife to squeeze it into the holes.

I winter in Ft. Myers and summer in St. Joseph, Michigan. It’s now about 12 years since I’ve joined this group. I gave my 1972 whaler to my daughter and sold the 17’. Bought an O’Day 28 sailboat and sailed on Lake Michigan. Yesterday I bought a 2005 130 Sport. |

I like using "Splash Zone" and work it into the hole, Works like "Bondo". Clean when green with acetone. If I plan on putting in a screw in the same place....a small thin splinter of teak or oak makes it way into the hole for additional bite.

There are better epoxy solutions than West if you go that route. Try System Three or MAS -- they are easier and more forgiving to use.

Blow with air a good idea...vacuum.....some reaming but not to damaged......get the loose, barely hanging on stuff out. Get down to good material. Make sure very dry, no dampness. For clarification, I use the "Splash Zone" on gel coat holes. For wood I use the two part epoxy. I found a hardware store "Loctite" epoxy instant mix product that mixes both materials in the syringe tip for a cleaner operation. I go with two (or more) applications to prevent a mess if filling all at once leaves a bad drip. In both instances I use a small splinter if re-using the hole. Too large a splinter and it throws off the pre drilling for a screw.

Be careful how you blow air in there. You don't want to cause the fiberglass to bulge and separate from the foam. When you clean out the screw hole its best to drill it just to clean it up. I have used those epoxy syringes to inject acetone in the hole. It will mix with any water around the hole and evaporate quickly. If you would rather use compressed air, go to an office supply and get one if those cans of compressed air they use to clean keyboards. Much less pressure.
