It is not necessary to wait that long. Once the epoxy has set it has more than enough strength to resist the tiny pressure you are adding wwhne you insert a few drops more of resin in an air pocket. You are just not going to generate that much force -- or at least I hope you aren't.

In fact, for a while after the resin sets, the glass/resin is quite flexible, and it is pretty easy to insert your glue injector through this to get the fresh resin in the void.

Any voids that are over 2 inches in diameter I do not fill. Same for areas I have totally screwed up. I sand them off, feathering the edges, and put on a patch which overlaps the sanded area. When these set up, I sand down the edgesof the patches, feathering them into the surrounding glass. Then I put on the second coat of resin, effectively filling the weave and also covering the mainsheet of fiberglass cloth, and any patches.

I am not a chemist who can tell you about chmical or physical bonding properties, but I know that if I do my patching after the first coat of resin, then the patches are covered perfectly by any succeeding coats, and can not be detected. The exception to this is if I sand too deeply. The first coat of resin colors the wood, and ehen I sand off the bad glasswork, If I sand too deeply I expose a lighter colored wood which does not return to a darker hue when the resin for the patch is placed over the area. Moral: Sand lightly, nd not more than you must. Best of luck to you. Paul Jacobson
