Making a half wall for my sx15 in my trunk. Just wondering the best way to seal up holes like my seat belt coming out of the rear deck so it still works yet is sealed as best can be. I won't be doing fiberglassing, only deadner, wood, and expanding foam. Thanks.

 

For the Seatbelt holes, get your hands on specially made SPL Tape.

As for other areas to be sealed without wrecking your ride. Check out my box instalation on my cardomain page. (found in sig) [img]graemlins/thumb.gif[/img]
