Probably the easiest way to clean is scrape the big gunk off first, then sandlast, or have it sandblasted. Nothing seems to really work well if you don't get the worst off before blasting or pressure washing.

 

Thats what i figured, so i am am just using a wire wheel on some to get the ruff stuff, and then an angle grinder with a low grit sanding pad for a lot of it as well. It works well, but i work slow and carefully so i dont take any chances of excessive heat or deep gouges.

 

The powder coater will want it blasted. He probably will do it himself. All the crud that gets into the frame rails will cook during the cure process. What a mess in the oven that is.

 

We powder coat stuff at work I personally would not use it on my frame... I would have the frame dipped and then painted with an epoxy etching primer and they have a frame paint that will holdup longer to road grime and rock pits. Powder coating chips bad when the surfice is not fully prepped and degreased. It also is porous and will get water under the powdercoat and will flake off with the rust. An etching epoxy primer bonds better to the steel and seals out all water. Just my two cents.

 

Epoxy and etching primer are two different things.

 

Nomad I do hate to disagree with you but we are both wrong here. There is a etching epoxy primer but it is used for aluminum. My body Guy says there is a paint used just for frames that is real tuff stuff. I am sure it is PPG. RYDEER If you want the info on this stuff I will talk to our paint Guy and get you all the info and part numbers that you will need.

 

I'm all set I did my frame with POR-15. I can't fit a sub frame in my oven or my blaster.

 

So the POR-15 works well and looks good on the sub frame? Got pics to show how it looks?

 

lots of pics in "new build thread" early pages

 

I found some. Upper control arms and Mtr Mts are powder most of the rest is POR. You can see in the 2nd shot before and after.
