i was pondering on your Tread title...   and realized I followed in your steps.... 

After painting some road wheels .... I forgot to MASK or cover them while spraying some Primer .... and yes....  Preparation and planing the execution.... is a must !!!  I FAILED !   cuz I Failed to prepare...

Lesson learned !   I hope ?

Keep up the good work !!!
