First father&son drive ... He just passed his driving test so it was time to drive an old BMW! Our Sunday drive to our local car club meet.

Most chemical strippers will dissolve portions of magnesium alloy, if the rims are magnesium alloy. I know nothing about E68 rims. Are you certain they are magnesium alloy?

 

Soda blasting is another option, provided you’re using soda as the media (if you’re blasting with sand as the media, you are “sand-blasting,” which might be overly abrasive, unless someone takes great care). I wonder if vapor honing is gentle enough — it’s sort of “media blasting with water”.

yeah I found a article online that said not to soda blast as it causes contamination in the magnesium. I’m going to see if I can find a sandblasting guy locally that feels comfortable working with magnesium.

Thank you.

 

I kept telling the media blaster at the time, “Gentle, gentle, gentle on the blasting.” But I thought they still cleaned my rims a bit much (first photo below). After painting, however, they were none the worse for their blasting (second photo below). The shop doing the blasting, however, was 3,000 miles away and I haven’t had any contact with them these last 8 years, so I don’t know what media they used.

Those came out great. Did they powder coat them?

Sandblasting and powdercoating is fine. I did that with both my Campys and my Italian FPS, also in mag alloy. No issues.

If you have the really porous Electron Campagnolos phosphate and wet paint is the way to go. Powder only works if done by a pro who tempers them correctly

Those look great Steve.  What are the widths and offsets on those bad boys?  They look awesome.  Which car will you put them on?  Enquiring minds want to know ?

Mine are painted. I know that many have survived powdercoating and look great, but I also believe I have little control over the oven temperatures my powdercoaters use, and I’m frankly a bit wary about magnesium alloy. I didn’t want to take any chances (photo below).

 

Mine are 5 1/2” x 13”, ET19, John. They currently have 165HR13 XAS’s on them. Had them on the ‘76, but I’m playing around with rims, again, and am trying something else currently.

They certainly do…. Those wheels are superb!

Me, I've just been piddlin' around painting lug nuts.  Thought I'd see how black looks.  I kinda like it.  Still waiting on Tyres...

Had a car show yesterday, had a fun time

M3This, does anyone near you do dry ice blasting? No one in Spokane does it, at least I haven't found anyone yet. 

Walnut or more gentle media like hot steam? 

Good luck. If I find anyone around here I'll chime in.

Found a dry ice place here but they said it won’t strip old paint. Really only good for deep cleaning.

Adjusted valves. Dyno day tomorrow…

Previously found a loose nut in the sunroof track. Turned out to be part of the height adjustment. Took the sunroof apart today and found the missing screw. Put it all back together and it works great.
