    Default Epoxy for filling holes in stringers.

    I have some screw holes in my stringers and i would like to seal them up properly before putting the new floor in. What is the best thing to use for this?

    Default Epoxy Not

    Personally I'd shy away from using an epoxy for filler or minor repairs. Most fiberglass hulls are made from polyester resin, so using a polyester filler would simplify the job. Clean up the holes you'd like to fill so the resin can get a good bite. Mix up a small batch of resin with an additive like West System #406 or #407. That will thicken it and provide strength, mix it thicker for horizontal holes and thinner for vertical holes.

    stubb , the bottom line is .....................if you can afford a little more money I would go with epoxy but that is your call and if you are going to go with a filler ( thickening agent ) I would go with Cabosil Fillers
    and the resin of your choice mixing it to the consistency of Mayonnaise which is moderately thickened or a peanut butter consistency which is a little thicker and often depends ( consistency ) on the person who is doing the work and might I mention that there is always a chance of a little shrinkage which might need additional putty if desired . Note , I have no use for Poly or Vinyl Ester due to work times / pot life & smell which are products that I very rarely ever use .....................but once again that is your call .
