I would recommend to all who have powder coating done to clean off all mating surfaces and check bolts are tightened again after use for the first time. With the powder coating being a thinker layer of paint than normal aerosol paint, it does expand/contract with heat.

Just check everything is tight once used a few times....

I know just have items shot blast then wet sprayed.... although powder caoting is durable and cheaper if you get brake cleaner on it... it fucks the finish up good and proper...
