I will not stand idley by and see these artriocities occur on my watch!! I will fly out to Ohio and take a can of whopass on you!~!
OK now your problem is fixed I feel better.
Seems that you will have to etch or use a special primer on the Aluimuim fork sliders to have a paint adhere.
Ok now I need to get over the fact that you are taking a BMW that was delivered from the factory in perfect condition and modifying. - Please consider UJM as an option. I know Ohio winter can be boring but get a life!!
