i use bondo brand resin from home depot, its cheap enough and if you get it when its fresh its plenty good for anything (fresh look more red then green)
i used a special mold fabric fleece from selectproducts for all of the stuff i've just posted. However, there is no problem with using regular fleece like what is available at walmart (about $3 a yard there for an ugly pattern- i just got 12 yards of penguins lol) except for its thickness. if your doing something fairly small you can't have the added thickness (say on kickpanels) that using that sort of fleece provides. In that case the select products stuff is far better.
as far as body filler goes, i like to use kitty hair stuff from whichever auto parts store carries it for things that still need some stiffening and strength. For finishing i use polyester filler from that same line. I think its the stuff they have at carquest maybe. I also just recently purchased some spray on polyester filler that i will be using on the larger pieces which should really speed up the sanding process.
ooh, i also get the "glass" fabric itself that they have at home depot, it is the bondo brand. I used it on those door panels when i did the strengthening for example, and it works great. the stuff with the big open rattly looking pieces is better for strength, and the tighter knit fabric is best for smaller pieces where you don't want a big mess.
i guess really i don't use anythign special at all- just the junk i can get within 10 miles of home. I don't put much stock in buying more expensive resins or fillers.
as for truckin' i know a staffer and i've been bothering him incessantly. truth is i probably will never be in there though
Gotta play nice
