: The lumps can be sanded off if-and-only-if they are not under the weave of

OOF. Some of the lumps might be under the weave. Hard to tell but I guess to be safe I'll patch with glass -- no harm if there's another layer in a small spot like that. Though right now I'm *sick* of glass and epoxy!!!!!

: My technique was to drill very small holes at
: each end of the bubble. I then took a syringe of epoxy and injected the
: glue into one hole until it erupted through the other hole. I kept up the
: injection pressure until all air was gone. Wiped it to keep it neat. I had
: to do this when I laid out the Kevlar in my cockpit. The bubble were
: bigger than a quarter but filled nicely using the drill/syringe technique.

I like this idea...my largest bubbles are much, much smaller than a quarter. Less than the size of a dime, actually. If I put a tiny hole in them and push epoxy through, that means no more messing around with frayed bleeping fiberglass.

: I hope this helps. What are you building?

Yes, this helps quite a bit. I am building a Merganser 16 from a kit. Been looking at other people's websites and find I have not made *every* mistake possible! But it seems like I've done something wrong or not-so-good at every stage of the build.
