Well I recently attended my 4th Thursday evening class
I have enjoyed each of the classes alot
I have a 1993 BMW 325i

At the Thursday evening class I applied Meguiars Ultimate Black to the following pieces
front bumper,B pillars, mirror trim, and rear bumper
^^ that was my first time using Ultimate Black
Before this I had always used Stinger Chemicals spray detailer in an aerosol can from my old dealership but that recently ended
The product went on smoothly and seemed to work great
On I believe it was Saturday evening Orange County got some rain and I woke up kinda late that day to my horror the Ultimate Black spotted up really bad
It was very obvious what had been treated with Ultimate Black due to the water spots
Is that normal for Ultimate Black?
Did I possibly screw up using the product?
Any thoughts and suggestions are welcomed
Thank you for your help
