Default Suggestions to hard coat a styrofoam Tric case

My new guitar came in and has a foam Tric case with no coverings.



It’s just bare styrofoam similar to the black type in a helmet.

I was wondering if I could epoxy or otherwise put some sort of coating on it to make it a bit more durable. It already suffered a couple dings on the way to me.

And suggestions would be great thanks.

Surely it would be cheaper to simply buy a nice new case.

Why? The case itself is very nice and super lightweight. It’s extremely protective but susceptible to damage of the outer part of the case.

I’m thinking just brushing on epoxy would give it a protective skin and shouldn’t cost anywhere near the cost of another case.

But maybe someone has a better idea of giving my case a durable cheap outer surface?

Epoxy might melt it - some cures are warm or involve chemistry which breaks down foam.

What about spraying it with a decent coat of lacquer?

Mmmmm yeah I was thinking of just a polyurethane or something too. I figured epoxy would be stronger however I have to use one that would be styrofoam foam compatible.

I have seen some people use 5min epoxy thinned with isopropyl and brushed on but that would be a bit expensive doing it that way as it would take so many tubes.

Default Truck bed liner

I have had good luck with spray on truck bed liner. You can get it in rattle cans or there are places that will spray it on for you.

Try it on a small area first to be sure it doesn't eat the foam.

I was talking with my friend about his car this afternoon and he was saying he is using Plastidip to protect the bottom of his front splitter from stone chips so that made me think it would be a handy solution for your problem. Spraying some of that on should do a decent protection job.

Default coatings

One of the best solvents to melt expanded styrene foam is lacquer thinner, or anything with similar chemical content. Dunno if spraying lacquer on the case would do anything besides melt it.

Anything that won't melt the foam and will provide any protection will be more expensive than a new case. There are finishes that will work, but they are not DIY or cheap.

I assume your guitar is a Seagull? At one time some of the Tric cases came with a sort of gig bag covering. The foam Tric case was enclosed in a gig bag. I don't know how else to describe it. You could see if those gig bags made to enclose the case are still available from Godin.

This... I don't know if you could get the "gig bag cover" separately somehow.

tape it completely with duct tape, then do the opening again with a cutter and you are done.


cheap and efficient, and nobody will dare to steal it

I stand corrected!

Actually had thought of vinyl automotive wrap which would be similar to the duct tape idea. (That’s not as crazy as it sounds.)

But since foam is used in surfboards, marine, model and prop building often with epoxies or resins, I’m certain there is one best suited that I can brush on that won’t melt the foam and is not overly expensive.

Most all epoxies are compatible with EPS.

I think I will get a small amount and do a test.

I’m sure I could epoxy coat my case for maybe $25-$50 of epoxy, maybe less.

Btw the case is for my Godin archtop.
