I gave it another shot today on a different part...its a stamped steel part.
I do have a water seperator in the airline before the gun.
I went through the same prep process of going to bare metal and ending in 220 grit sanding finish.
I heated the part with my hand held heat gun first, and then coated the part with the same black powder.
This time, I put the powder on about 3 times as thick as I was previously.
I set the oven temp to about 375 and baked the part for 20 minutes. Shut the oven off, propped the door and let cool.
I got much better results this time. The finish was a little "Wavy" but much improved over my previous attempts.
As a second attempt, I sanded the finish with 400 wet and applied another coat of the black....laying it on thick.
I used the same oven cure process, 375 for 20 mins) and I got good results again. Not a perfect smooth finish..... still a little wavy...but
I think I am on the right track.
Thanks for the comments....and if you have any other ideas or tips please let me know.
Thanks,
Eric
