WHats up guys. I'm gathering all my materials to start some fiberglass projects. I've played with fiberglass before just to get a feel for it and have used Bonda brand body filler and what not but i've been looking at Evercoat brand items. I'm trying to figure out what the difference is between a body filler like Evercoats Rage line, or a reinforced fiberglass filler like Everglass. I know ones a body filler, the other one has fiberglass trands, etc etc, obviously, but what would you use each for or are they basically they same thing? Thanks

hey steve, im new to the org but i worked in a body shop since i was 16 and i am currently finishing school for collision repair. to awnser your question a fiberglass reienforced body filler has strands of fiberglass in it. the strands make it stronger and builds higher, fiberglass filler is also waterproof so it is great for filling small holes. The other body filler is polyester filler it has a lower build but is easy to sand and finnishes nicely. However in eather case your total thickness of filler should only be 1/8 in. i dont know exactly want your working on but if you need high build i would use 1 coat of fibeglass filler ,then 1-2 coats of polyester filler, then a final coat of glaze putty. the fiberglass filler leaves behind pin holes so if you use fiberglass filler you need polyester filler over top. but if you just filling minor imperfections polyester filler will be fine. as for the evercoat brand i highly recomend it ive been using it for a while , good stuff.

cool man thanks

i had some experence with 3m parahna body glaze...that stuff was also pretty good

I've never used the evercoat rage line but bondo is a most common. Mat, is used if you have a large hole. Or your working on some plastics i.e. bumper, skirt kits that has a crack in it. There are two types of fibreglass you can use weaved glass and loose . weaved is stronger. Good for reinforcing has a backing for a hole. Loose is good for contours, filling etc. make sure when using the polyester fiberglass resin to wear gloves and a (NIOSH) approved mask Styrene oxide is listed as a carcinogenic Anyone that works in a bodyshop giving advise on working with resin should tell you that first off. If ya wannta get high smoke weed cause this stuff will kill ya I've seen it happen #2 Reinforced fiberglass filler. This stuff works as a good filler after applying a weaved fiberglass backing on a hole or on a fresh grinned rust spot and you want to build up that area close to the contour of the car (stays better than just plain bondo) also works good/fair on some plastic parts I normally use it after grinning down weld lines and rust 24grit 40g 80g <<<sticks good. Normal bodyfiller is good for very small holes and final filling of low spots and some pin holes. Pin hole some times happens from mixing too hard and to fast. air gets trapped in the mixing and some times can't be avoided. for that I'd go with a "skim" coat of glaze putty. Too much and you'll be sanding and gumming up the paper. My bodyshop just uses a 2-stage primer that fills in alot of imperfections. but if your doing it from spray cans go with the putty and a scratch filler and primer spray...Good luck let us know how it turns out
