since we are talking about combatting the rust...
my cavernous wells were repaired with about a gallon and a half of fiberglass resin jelly, chicken wire, fiberglass mat, and some sheet metal and rivets, a coat of POR15, and a coat of non rubberized undercoating, im going to check it all after winter and see what i have to go back and redo. i know the wheel arches need some help, i accidently hit one iwth my bowling bag and busted a small hole.
wish i knew more about metal work when i did this but its pretty damn solid at its current state.
