Help needed! Eps dent pre glass

So I took the day off work for my birthday to finish up board number 2.

I have the tape all layed out for the cutlap, and as I'm moving the shaped blank to the glassing rack to get started I hit the nose against the edge of a shelf. I felt my heart drop as I knew I had just f-d up.

There is a dime size dent in the rail up on the thin part of the nose probably about 1/4 inch deep. My first instinct after letting out a few curse words was to glob on some fast n final and sand it back down. It seems to dry just about as hard as the foam itself. It's sitting out in the sun right now to dry.

 

Will this fix be sufficient to glass over, or will it cause a delam down the road? I would post pics but all you will see is a big glob of fast n final on the nose rail.

Spackle may not be the answer, it will take forever to fully dry in a big blob. I'd just replace the foam with more foam, one tiny drop of gorilla glue will hold a patch in place (keep the glue on interior so it doesn't show).

Happy B'day!

hey MD, do you think a heat gun might have worked here?

Thanks Mike. Since I already globbed on the spackle before your reply I might give it a night to see how it drys. If not I will cut it out tomorrow and replace with a new piece of foam. There will be a resin pigment over the rails so I don't think any of it will be visible once glassed.

I tell you, it's a terrible feeling doing something like this to a finished blank!

ouch. I’ve used an iron on a low heat to bring out small dents…

chrisp, the heat gun works wonders on pushed-in PU, but don't do it on EPS. (don't ask me how I know this, lol)

those little dents drive me crazy.  that's one of the reasons I don't let people in my shaping area.  they always want to touch the foam and then they dent it and get finger prints on it.  makes me want to kill them with my planner.  I don't think anyone would blame me.

Do not use Hot glue either. Same ask me how I know.

 

Well it would be better described as a gash except the foam didn't tear. I gave up on trying to glass it today, I'm going to try again Saturday. I will post pictures once I sand it down.

 

Hey Greg.

You’re scary, MMA style…lol

I hope I never meet you on a “bad day” with your planer in hand…Run, Kiterider, Run…lol

Actually I keep sanding away the eps,  until I allow for the thickness for my   A 400 / A 500 core cell skins,   Little dents in the interior core eps are of little concern, when they’re sandwiched by an outer skin of  Core-Cell…You finish sand the core-cell exterior, then glass…

 

Glass the board first then fix it.

Foamball:

Sounds like you got some good advice.  Consider yourself lucky in that you can have the spackle dry in the sun.  You could be living in the Chicago suburbs like myself!
