filler to use before powder coating

i was wondering what filler i should use for some slamm low spots on a part that is going to be powder coated. any help would be sweet.

im jsut guessing. but im sure its needs to be a metal filler like all-metal or something similar. i dont think the plastic fillers would hold up in the oven

well finally something i know alot about haha i just powder coated the whole exterior of my truck i used all metal body filler and you have to add alot of hardener and let it cure really really good. should have no problems at all i only had one issue with not enough hardener but now i know how to do it.

Josh are using evercoat metal 2 metal? This would make my life a million times easier for the dually project....

Check out www.columbiacoatings.com they sell a filler

cool thanks josh, so you are using the USC all metal. when you use that can you sand it or do you basicly have to use a grinder?

Also you can use KL primer, its a powder primer that can be put on up to 20 mills and sanded smooth.. I use all methods mentioned. any questions ask, powderfx@live.com

Probably not the best, but I have seen plain ol Bondo used.  It bubbled out when it was hot but when it cooled down you could not tell.  It was on the side of a dust collection unit that was return because of damage in shipping, when it pulsed the side walls shake pretty violently, and it has not come off yet.

also lab metal one part no mixing works awsome
