Product review (5 stars): Seems good so far!
It's only been on for a few weeks....but so far so good.  Has a nice finished to when it's all dried.  Smells pretty awful when applying....but that's how you it's working, right?  Be sure to clean you areas good  before application.  In fact, some spots, I opted to just cut the spot out and have really clean metal exposed.  Way cheaper than buying a whole rack.
