Wall thickness advice

[Flipper245]

So I put an infinite baffle wall in my hatchback. I cut the back out and stood it up. fiberglassed in top and side panels. It's in very strong and sealed well. Airtight and all that. Works and sounds great. Woofer is 78 pounds. Baffle is 1.5 inches. Too panel is 1 inch and side panels are about 3/4 inch. I've seen that most walls are thicker. The baffle is braced very well all around where the woofer is bolted on but I'm questioning the top and side panels. Instead of cutting more wood, can I use a heavy body filler to thicken it up a bit? The back side is very ugly also so was hoping to pretty it up a bit by doing so. Maybe use some bondo with glass in it? I figure it would be way easier than putting a few layers of fibreglass. Any suggestions?

As long as it's not structural the body filler is fine..

No not for structure but the panels i will be putting it on are a bit but mostly just to keep rear wave from coming back into cab. Just want the filler to help with that. Thanks!
