[Shop-talk] powder coating

[Tim]

The guy told me that they baked my wheels twice. After the second bake 
off and then the second powder coat he said they looked better but was 
still a little bit of bubbling and then still the pitted spot.

He said they are going to order a fresh box of that color to make sure 
it isn't the powder and then do hte process again. Hopefully third time 
will be a charm.
