RE: Fuelproofing the firewall?
Elmer's glue.. No, JB weld/epoxy should work, But really you do need to
thin it..... I just got some fuel proof spray paint and mainly sprayed the
bottom of the fuse with a few coats.. I drilled a drain hole just before the
bulkhead not only to get the fuel out, but so I could see any problem as
fast as possible.. I got my paint from the hobby shop, But I'm sure you
could get some at hardware/walmarts etc...
