when the body shop installed a new drivers side lower door hinge in my door they cut out a kinda rusted panel of the cab right in behind it (towards the front of the truck). it directly faces the front tire so it sees alot of water. unless i fixed it water would splash on the hinge onto the door and drip onto my running board (which i have drilled drip holes thru). you'ld have to be a magician to put sheet metal there, make a paper mache' mold to copy then bend it and it's kinda curved, like holdinig water in both hands. i am trying this fiberglass mesh i got from the plasterer that is used for "eifs" exterior insulation finish system. its like 1/4" squares and not too stiff, very bendable but not wishy washy and cuts easily w/scissors. they have thicker stuff that is sorta hard to bend. i didn't use that (panzer grade) but the other (medium grade). they are both way stiffer than any fiberglass mesh i've seen, and glass would just drip right out of these holes. since all-metal is spozed to be water proof (ive seen some 5 years old on a rusty vehicle that hasnt even started to fall apart) i decided to torture test this stuff and build a (hinge cover)if you will for my cab. mixing a tiny bit at a time i attached the bottom of the mesh onto the metal that i ground to bare metal, and let dry, then the top and sides. then i gradualy coated the whole peice a little at a time till it was solid. the whole thing could have been fiberglass but i've seen poor adhesion with fiberglass and metal-at least when i do it. anybody think this will hold up for long? i was planning on spraying rubberized undercoating over it but am tempted not to just to torture test it. it looks totally perfect, except for being silver. i have an extremely rusted out 65 pick up that i would like to see towed away that if i get stuck with having to keep, i want to try this technique on a lot larger scale, such as re-building the lower fender quarters, bottom of doors, etc etc. any thoughts or experiences?
