...remember to get the black screw head cap/cover for your first aid box bracket in the trunk. I mean...you've come the far. :D

Thanks Hunneman and Leadphut.

After multiple failures trying to refinish the very flexible rubber spoiler on the Alpina I finally came across a good solution. The problem is with the paint cracking. I tried many different flexible paints and primers and initially they all looked very good, but after a few weeks I noticed hairline cracking that eventually kept growing. The different rates of expansion between paint and spoiler and possibly slight flexing from the air load is my guess for the cracking. A spoiler with an integrated rigid component like on the M5 and 535is may have better results.

The first step was filling in the various pock marks in the old rubber. I used crack filler from Leatherique, the company that makes products for seat refinishing. The filler is flexible and adheres well but requires many layers because it shrinks as it dries. It also works well as a skim coat. The paint I used is ProLine from DipYourCar and requires an HVLP spray gun with a recommended 1.8 tip. It’s essentially rubberized paint. The primer goes on clear and the matte black finish has just the right amount of sheen. Unfortunately, this paint is only available in gallons. Some use the rattle can Plast Dip which will work but the finish doesn’t flow out nearly as well.

Another re-sanding after paint cracking.

Over 7 months and no cracking.

That's impressive. Well done.

And thanks for sharing the technique! I bet this will work on the standard 535is spoiler rubber just as nicely.

Great job.
I know David's car well as he is a close friend.
Love me some Alpina's.

I just bought an 87 E30 B3 2.7. Diamond Schwartz.
Came from Japan in 2012.
Bought from friend before he died from cancer.
Estate is settling and don't have car yet but will get in a few months.

A guy named Mike Gray had a E28 B6 I believe and sold many years ago.
Not many around.
Hope to see it someday.
I grew up in Maryland but haven't been their since 2015.
Take care,
Gary

Beautiful. I am doing much the same right now. Did you repaint any of the Alpina valve cover gasket, intake plenum or intake pipes? If so, what paint did you use? I'm hoping I can find a BTDT so I don't need to go by trial and error. I too need to find the silicone couplers but I think it's just a measure and shop sorta thing.

I was told that the E28s didn't have air conditioning because there was no space up front for the condenser with the intercooler. I have never looked around to see if any others had it. It may be erroneous info. Also, the air filter and straps are Porsche 924 but I think everyone knows that. I was told that the rear muffler is from a euro M-car.

KSK/Alpina parts are crazy. I had to buy a brass fitting for the wastegate adjuster 20 years ago and I think it was almost $200. It looks like something you could get at Home Depot for 97 cents.

Beautiful car. It's inspiring me to be more fastidious in what i'm doing.

Thanks, and yes I did repaint all the engine stuff. I remember I tried multiple products until I was satisfied because the original paint looked like a hammer type finish to distract from the rough casting marks. I know I took notes so I’ll get back to you on this one.

These cars did come with AC from Alpina. EAG has a factory AC car for sale now if you want to see what it looks like. The giveaway is where the lines enter thru the custom (Alpina) firewall panel. I’m counting over 40 Alpina part numbers in my catalog that make up one of their factory installs. Imagine what KSK would charge for that bunch if they were even still available.

What number B7 do you have and for how long?

Thanks Gary,

Did you take delivery yet of the B3. Post a pic - love to see another Diamond Schwartz Alpina.

Stopping by as a vulgar ignoramus, not worthy of even sitting near the Alpina owners' table, just to scream OPEN LUG! 16 INCHES MAXIMUM! and run away before Security gets called

Possibly you can PM me here or email me at dlvad@yahoo.com I'm unable to send PM's as I have too few posts since 2009. That is of course you receive a notification of the new post. :D

Thanks.

I did not get the car.
The estate backed out of the deal.

It was a really nice car and now has sat for over a year.

I do own a 72 3.0 CS that I restored.

One day maybe I will own an Alpina.

Kapt: Which color of the ProLine did you use? If I zoom in on your picture, all I can see is the word "Black" (maybe as part of an incomplete color label), but on the ProLine website, they have two blacks: "Arctic Black" and "Volcanic Black." Did you use one of those two?

Edit: My mistake, there are THREE different blacks you can buy: "Arctic Black," "Volcanic Black" and "Onyx Black." Which do I choose to match a factory IS spoiler??

Actually it’s none of those. I found the basic matte black was very close to the original color and sheen. Also, it works better if you use their primer. Here’s the link.

Did you have the steering wheel recovered? or is that original. I have the same MOMO wheel(except Hartge) that needs recovering, and I don't know who to trust to recover it correctly.

The steering wheel is new. Unfortunately I don’t know of a place to get your wheel done.

check out roaddefined on instagram. i have the same momo (without alpina badging) and want to send it to him, his work looks really good and he provides tons of materials to rewrap in. just has a steep price, around $440 before shipping
