I have not heard of epoxy taking on water, but if you sanded away too much epoxy and the fiberglass cloth was not saturated then that might leak. Post a pic if you can. You might try spraying the area with rustoleum, it sands off easy enough when you go to do more work.
Marinetex will do it... the mariner's version of an auto mechanic using JB WELD. For that matter, JB Weld makes a white version marketed to boaters. Your hull ding, if already patched on the inside, could be filled with some Marine Tex.? It has a very short working time so you want to be ready to smooth it out well as applied, to save a lot of sanding later (marinetex is hard to sand.). I think it could be thinned with a little alcohol or whatever is recommended on the package for clean-up, thinned out a little from it's peanut butter-like texture, you could smooth it easier.?

No.? It didn't occur?to me.? I thought epoxy alone would be a good patch.
Is there a spray on something that would be good enough on top of sanded epoxy?? Or something like that?? Maybe some paint?

Did you try gelcoat over your patches?

I want to thank you all for your advice and help.? In particular, "Clark and Skipper" - your tutorial on a blind patch really did the trick for me.
My goal is to get the craft sailing again - not to look the best (yet).? So I cleaned off the bottom - and found the patch I sanded was letting water in and out.? Now I could have done a better job and plan to fill in with thickened epoxy.? But I am wondering now if sanded epoxy takes on water?? If so, I need to seal these patches once I sand them down.? Can anyone recommend a water - tight spray primer???
I may?paint the whole bottom later.? But in the meantime, summer won't last forever and I'd like to sail him (yes, I know boats are usually named for women, but my daughter christened this one "Alan" - I don't know why).

Put a blind patch inside the hole and let it dry. Then build layers of fiberglass cloth up on the patch, fair, sand, paint (or gelcoat)
