haha! nice, but only for one time use!! but, at least you can eat the 'taters after your first ride...... anyway, i found some inexpensive packing on ebay. i left the packing a little loose and little bits of it got blown out the seams. so, if i were to do it again, i'd go a little tighter/snug. as long as you have something in there you're better off than the empty tin can rattle that hollow ones give. but, like you've already found, ownes corning is only reliable for your attic.....
