I work on my boat each night and Friday, I started filleting. I started at the stern and moved forward. I added the first coat of unthickened epoxy to the stern area on Friday. I forgot the manual said to apply the second coat within 72hrs and I'm over that limit. If I lightly sand that area, will it be OK to add the 2nd coat? The rest of the boat I coated last night. I'll add the second coat to the rest of the boat tonight.
