In Response To: 2nd sealer coat or glass? (sage)

:One large crack the epoxy ran through the hull.
: Epoxy will not run through now. Most of the the cracks are less than 1/32
: wide. Should I do a second sealer coat or should I glass next. Will
: glassing leave voids at the cracks?

Go for the glass now. The fill coat did its job and filled the cracks and the wood pores. Why add another coat? You would gain nothing. Any cracks that seeped resin with the fill coat will simply take a few drops more resin this time, and fill to the brim.

If you are unsure that a crack has indeed been sealed by the seal coat, reach inside and cover that area with a piece of masking tape. This will ensure that you don't get any resin dropping through and leaving a part of the glass cloth starved for resin. Pell off the masking tape after one day. By then the resin will have gelled enough that it won't flow, but it will still be in a "green" state and easy to clean up the drips.

Actually, if you have not yet done so, you should scrape off any drips that are on the inside while they are still green and easy to pull off with a scraper, before you put on the glass cloth. They get harder to remove as the resin continues to polymerize.
