You have a local shop do your powdercoating? I'm always worried about giving stuff to motorcycle shops and places of that sort as I'm always afraid they will coat something that isn't supposed to be.

Crystalworks unfortunately I do not have a local coater that I would use for the valve covers. The outfit that I use is Custom Powder Kote out of Michigan
Home and they were recommended to me years ago when I was into muscle car restoration ( I had a number of 70-73 Trans Ams and formulas), days before I got into German machinery. Anyway they did a number of parts for my Trans Ams and when I crossed over to the German cars I read the number of problems people would have with refurbishing the magnesium valve covers of the BMWs 4.0/4.4/4.6. When I spoke to custompowderkote they mentioned that most of the powder coaters do not outgas( bake them at 400 for a while to get the oil out of the metal) and thus causes adherence problems with the coating. CustomPowderkote gets the oil out of the metal and blast beads the media before coating. I have done over 6 BMW valve cover sets with them and oldest one is now going on 7 years on my brothers e34 540i m-sport ( use to be mine 4 years ago) without a flake or chip. They have a good turnaround time and I trust them.
