JB weld to smooth frame inperfections prior to powder coat

[DEMON DAVE]

ok unless someone has had a bad experience using JB weld to smooth frame inperfections I plan to use it as it will take the that a powdercoat over puts out.
any thoughts?

I have used it with great success you need to use the long set stuff it has more metal in it. Thats Directly from my powder coating guy.

does the long set stuff shape well ? and sand down easily ? ill have to check auto zone for the long set stuff

It sets up ok but takes about 12 hours to fully dry. I used tape to keep it moulded in place then sanded it how I wanted it.

I use the high heat stuff and it's always worked well for me with powdercoat...I assume we are talking the putty?

JB Weld makes the stuff in tubes. One resin the other hardener. They make this in the regular formula and a Kwik Set. The Kwik Set won't take the heat of the oven as well as the regular stuff.
I don't know about the putty stuff, never used it.

Ask your powder coat if he has a primer. My coater has a primer he sprays, bakes and then you sand it like a high build primer. I havent used it but he says it works well.

Good information here looking to see what all works well sounds like some good solutions for making things clean up nice.

I also researched "lab metal" that looks like a good option too , just have to see where its sold at .
the factory frame has many many inperfections in it krappy looking welds , dimples everywhere , but im use to seeing aluminum spar frames and late model dirt bike frames that are crazy clean in the assembly process
