I shaped and glassed my first board and it came out great…or so I thought. After glassing and sanding I noticed some thick resin like substance oozing out from under the glass (after a hot coat) I thought this maybe some kind of venting issue because its an EPS blank, so I drilled a hole in the glass and that didn’t stop it.
I decided to leave the board alone for a while and come back to it, and when I did after it sat in my basement for about a month there were dark yellowish/brown marks on the white areas of the blank and especially around the fin boxes. I used proset epoxy (because I got 5 gallons for free) with the west system clear hardner. I called the tech people at the company that makes both products to ensure their compatibility.
I’m now thinking of doing another coat with RR and opaque pigment to hopefully hide the gross coloring and stop the oozing. Bad idea???
“stop the oozing” - what does that mean? After a month, there is still a “resin-like” substance oozing? (does “resin-like” mean that its not actually resin?)
both companies told you their products are compatible?
can you post pics?
what is your glassing schedule?
who made the blank?

what are the “white areas of the blank” - the whole blank isn’t white?
what did you set the fin boxes with?
sorry for all the questions, but it seems to me that more info is needed to really understand what’s going on
that board is DOA. Gotta test that resin & hardener pairing on a scrap block before glassing your board. Sounds like ratios are off/incorrectly mixed duing your lam stage or both. Don’t waste your coin coating that blank again. Lesson learned, build another, built it lighter, stronger and buy enough hardener to match your free vat of resin. triple check your mixing ratios, and test, test, test.
EPS doesn’t have a venting issue persay, it doesn’t ooze or expell anything. It’s white beads through and through. Something either contaminated your blank or you have a resin issue.
…or the off-chance your neighbor has foiled your plans and injected motor oil into your board with a syringe. Sabotage is a real biotch, be weary of jealous neighbors trying to stifle your cool work.
Didn’t complete the stirring. You had areas in you cup that were unmixed. Gotta be careful about corners. Ride it till it dies and chalk it up to experience. You won’t make that mistake again.
