Covered it in suede. Plus strength is tried and tested. This box has been going tough as a demo car for 2 years now. 0 issues in strength ir performance.

yea im not saying it isnt strong enough for some installs, my point was that actual fiberglass is still stonger. hell i made some pods a while back for some tweeters out of a thin layer of fleece and soaked it in resin and you can probably hit it with a sledge hammer, i was really surprised at how strong it was after just one layer. plus the fact that your box has nothing but curves also has a lot to do with why it holds up nicely, if it wasnt so curved it would probably flex a little.
honestly if it flexes now you wouldnt even know it because its covered in suede, if it was painted, that would be the true test of whether or not it flexes.

Well I was just throwing this process out there. It IS strong. And it ran painted for a few months before getting wrapped in suede. No flexing. Glassed clean through over 1/3" thick. It worgs great when you need curves and a slightly faster process.

No harder than sanding any other fg application.

speakermakers do you remove the hardboard after the FGing or just leave it? I would assume that the FG just bonds to it like wood?
The best tool in my work shop, is my BRAIN!!!!

I guess there have been a few points of confusion on my original post.
    What Fatmat is
    How I use chip board
    How this technique saves you time sanding
When I refer to Fatmat I am not refering to the sound deadener product. Fatmat is a term used in large production fiberglass industries like boat building and hot tubs. Fatmat is a technique where you pre-layer modified twill with random chop mat using solvent based spray glue. This allows you to apply resin to the fiberglass before putting it on your project. Doing it this way also allows you to roll out any excess resin giving you the perfect resin to fiberglass ratio for an ultra strong and light wight product.

Yes I remove the chip board. I tape and wax the chip board before I lay glass on it. I then bond the glass back onto my project. My projects are much lighter weight and much stronger than you will typically find in the car audio world.

This technique saves you time sanding. Because the glass is preformed and rolled smooth. The final layup requires much much less body filler and consequently sanding. As an added benefit the project has dimensional stability. It won't warp in the sun and there is not much filler on it so it won't shrink and show sand lines through the paint work a couple of months down the road.
