Hello gents,
Let me say that this is the 3rd or 4th box I'm building, but it's my first time with fibreglass so if any of you can chime in and help me with a couple questions it's greatly appreciated.
So let me begin by saying that I made a frame for the box, taped the inner wheel well and began to apply some resin with fibreglass mat. I'm happy to say that this first step went pretty well with the exception of not adding enough hardener to make it cure as it should, but everything worked out.
Now, I added a couple more layers of resin and because the box didn't feel sturdy enough to me I wanted to add a second layer of fibreglass mat and this is where things got messy. I ended up applying them just fine and they are currently hardening, but there is a TON of air bubbles below the fibreglass mat.
I don't care if it looks ugly on the inside (obviously) but I want to make sure it's air tight for a good sealed encloser.
1) Am I okay to sand it down once hardened and add an extra layer of resin to fill any holes?
OR
2) Can i put body filler on the INSIDE of the sub enclosure to help seal it up? Would the vibrations make the bondo brittle and break if I did this? First time with Bondo too.
Thanks for the help!
