i used Por 15, its a multi part system. I taped up a few things but i also had the front suspension out of the car when i did it. As long as you follow the instructions you'll be fine, top coated it with black bedliner to give it UV protection.
I know everyone likes pictures better then words...
All my engine parts are currently being coated by Signature Products- Valve cover, catch cans (4), hella grills, brackets and few other pieces that he is coating. He will also be fabricating a few custom pieces for me in his new shop...
also raised my suspension, my coilovers were so dirty after a full summer of driving it was crazy. Glad i have a parts washer and patience...
well i know its not since i took mine all of the car and completely washed them in the parts washer and they are not leaking any fluids. all i know is that coil was the dirtiest of them all and was one of the easiest to clean off. but i also get my car rustproofed every year and that s*** goes everywhere while they spray it..
