I know this isn't exactly about car audio but I'm getting ready to make a custom PC case. I was thinking about making the entire enclosure/box out of those green floral foam blocks.
Now keep in mind I'm a n00bie. With that said here goes nothing: Which matrial should I use to harden the foam (I was thinking about coating/soak it with fiberglass resin)?
I've done some research but I'm haven't found anything. I should also mention that the final enclosure should weigh just as much as a normal plastic case.
