I stripped the paint from my valve cover this morning with a spray stripper and repainted with Harley Davidson engine paint that has a crinkle finish. Stripping th paint tokk about 30 minutes, masking off all the lines and letters took over an hour. The paint went on very easy. So far I am VERY happy with the results. I am baking it in the oven at 180 for an hour as they say then removing all the tape. For $15 for the paint and $5 for the stripping spray and two hours work it looks to be an excellant solution instead of powdercoating and alot cheaper. I will post pictures afet I get the cover installed back on ther car.

Steve... you may also want to let it bake in the sun for a day or two as well.
I've heard lots of people have success with the harley Davidson paints..

Did you do the plenum as well?

I didn't do the air boxs yet. I want to see how this turns out first. The air box is in pretty good shape without any peeling. At least now I can raise the hood and not be embarrassed about the look of the engine now. Buying Gregs car and his addiction for detailing cars, came with the car, clean this, repaint that....

You should be able to upload pics, unless Richie has turned that option off. The total attachment size is limited to 512k. So if the images are large you will need to get the file size down to be able to upload. You can use multiple posts to get multiple images up.

Hope that helps,
Brian

If this paint is going on a magnesium BMW cam cover, well, paint doesn't stick to bare magnesium very well (from what I hear from my aircraft fanatic friends). And of all of the hard driven BMW road warriors I have seen, the factory (painted) finish on these magnesium parts doesn't last long, either. Apparently the trick with magnesium is anodizing...

http://www.finishing.com/faqs/magnesium.html - learn more here

http://www.bookrags.com/sciences/chemistry/anodized-surfaces-woc.html - and here (see excerpt below)

Among the metals that are often anodized, magnesium is notable because the untreated metal is so very readily corroded. Anodization of magnesium provides a hard, corrosion resistant surface that is also highly adhesive to paints. Magnesium metal has a low density and magnesium alloys are critically important in the aircraft industry, where integrity of the metal and prevention of corrosion are a must.

A quikie Krylon (spray paint) job sure is cheap, though, and a simple touch-up every 2 years isn't hard. But for long lasting, durable paint coverage, anodize the magnesium first.

Of course, later BMW engines ustilize a plastic cam cover. If that's what you have, paint away,
