Title: Question about BMW Paint
Post by: paratrooper34 on September 01, 2018, 06:50:09 PM
Hey All,

    I have been doing some odds and ends to clean up my '88 K75S and noticed a couple of strange things about the paint.  First, I used some rubbing alcohol to clean off a spot to apply a sticker.  I was very surprised to see that it actually removed some pigment.  Never seen that before.  Then, I had some spots in places that needed some rubbing compound help.  I used the compound, then a polishing agent, and finally applied wax.  Each step removed pigment, even the wax.  I expected the rubbing compound to remove some pigment, but was shocked to see the polishing compound and WAX remove color.  These were all McGuiar's (sic?) products.

    As far as I can tell, this is original paint.  There is no evidence of a repaint.  The paint was not completely removed and the final finish is actually pretty good.  It shines nicely and I plan to finish off the rest of the bike.  Question is:  is this normal?  I have never seen pigment removed by wax or rubbing alcohol.  Strange.

You can get BMW moto colors in a rattle can that look pretty good if applied well but they won't stick like OEM unless covered with 2 part clearcoat.
