I'm a novice builder working on a 12' Michalak Piccup Pram: stitch and glue, taped seams, marine ply... I have taped and glassed, and I'd like to finish sections of the hull bright (the pram has a prominent flat bow transom and bilge panels). However I have some less than perfectly fair spots, two or three air bubbles at seams etc.
Can anyone recommend a pre-made filler OR a means of thickening epoxy sufficiently to patch / fair these spots while maintaining sufficient translucence that it'll look OK when finished bright?
(I have built a taped seam optimist, PDR, and done repair on fiberglass hulls, but my epoxy skills are quite modest! None of the filler product for sale seem to be transparent; and all those I've mixed into epoxy (microballoons, sawdust, silica) would rule out bright finishing. One idea I haven't yet tried is thickening with chopped glass; I'm assuming this will remain translucent, but maybe it will be too hard to thicken it sufficiently in this manner to properly patch and fair.)
