Dear Experts and Hobbyists,
I have a number of magnesium intakes and valve covers that I wanted to coat. They initially had epoxy paint from the late 1980's on them. It is very hard to remove even with aircraft stripper. I was told that preheating the parts to about 350 degrees F would help to crack the paint. Then I was told to use aircraft stripper.
Any recommendation on removing the paint? Remember that cast raw magnesium is pretty darn soft and doesn't like media blasting.
How best should I prepare the magnesium to get the powder coating to hold for a number of years. Is out gassing a needed process and how long and at what temp do you outgass?
Also what type of oven should I get for my small shop to do the powder coating of intake and valve covers? Is a traditional gas or electric oven a good choice for small parts?
I know how to paint quite well, but know little about powder coating. I would appreciate all and any advice on equipment and supplies. Sorry for all the questions, but I am a newbie to powder coating.
