I really like the sem line of products , we use them in my shop all the time...Their rust shield is some awesome stuff too for under carriage (compare with por-15)..I have seen a buddy of mine use sem rustshield (black ) on a dash pad and door panels of a 67 firebird he was changing the color of the interior on ,gold to black, he sprayed it with the gun , masked and cleaned it properly first but man , it came out Great!!! I thought for sure it would look like crap i was wrong it came out looking like they were new!Couldn't believe it..said he learned that trick in some body shop out west he worked in , held up great for the almost 2 years he kept the car afterwards.Some tough stuff there..
Transtar also makes some good interior paints...
