From an abrasion standpoint, the grahpite coating holds up really well. Besides the Slip Plate (which I think got a new name recently) there is an identical coating available at places like Tractor Supply. It's in green cans and is called EZ Slide, it can be found in the isle with baler parts and stuff. It's a great coating for frames and springs. I've considered painting a truck with it.



to be honest... I'm in a bit of limbo these days on my approach in some regards... I still feel a good zinc wash, urethane primer, topcoat is the best coating procedure... as opposed to an epoxy/poly approach...
Fram and Champion have been banking on that chit for decades... Duplicolor, etc can all fall into that too....
