I am making a custom 'glass enclosure for the back of my truck and I have the skeleton made out of MDF and I have the top covered in fleece. I have a rectangle base made of MDF with dowel rods holding the speaker rings floating above the middle of the soon to be enclosure. After I apply the resin to the fleece on the top and layer that up I am wondering if there is a good trick/method to glassing the bottom (obviously needs to be air tight). I plan on putting body filler and painting it if that matters. Thanks.

why dont you make an mdf bottom??? If that is not an optiion because of curves and such I would pull it out and stretch fleece then glass it as well.

I was going to 'glass it because there are metal ribbed looking pieces for a bottom (the floor of my trunk) and i wanted it to fit with those nicely. Should I stretch fleece across the top/places you can see, and staple it to the bottom of the frame, 'glass it for once for strength, then pull fleece across the bottom and staple it to the side so I can hide the staples with layers, then cut out the speaker holes and 'glass the bottom from the inside?

I would take fleece stretch across bottom of frame. Staple to bottom of frame, like the edge of the mdf, that touches the floor. Then I would sit it in the truck how you want it situated. Then I would reach inside and put resin on the fleece from the inside let it cure fully. Then you can pull it out and glass on the inside or the outside of the box. "MAKE SURE" you put down some aluminum foil and tape though before you put resin on the fleece on the bottom. If you dont you probably wont be able to pull the box out ever again.

Alright that sounds like a good idea. Thanks for the input hopefully I'll have some pics next week!

Always do the bottom before you glass the top. Aluminum foil works awesome, use the heavy duty kind.
