Decided to have my valve cover powder coated. The coater sent me these after the initial coat and before clear powder.
Clearly there was offgassing. Seems unacceptable to me and would appreciate input. The coater took no blame and said it was out of their control.
My understanding is the metal should be preheated prior to coating to avoid this, or to use a powder that stays fluid longer to prevent this.
They are saying "there is a chance sanding it and re coating will not fix it. It is caused from impurities in the metal gassing off while it is heating up during the curing process. We often see this in cast products and is out of our control. Coating it a second time will be another $95 charge."
Seems they should fix for free.
