Was thinking of having some trailing arms powder coated. Got two estimates from local shops. Cheaper one claimed that they didn't need to put a primer coat on before the finish coat as it wasn't necessary, the finish coat adheres well enough by itself. More expensive shop claimed that an epoxy or polyurethane primer was absolutely necessary. Any advice from the past experience out there?
Thanks, Andrew B. |

Brett,
Something like Skyco Ospho (sold at Ace Hardware), MetalReady (by POR-15 or Eastwood for under their flavor of rust treatment paint), or something like that. They're all spray-on, rinse off. Columbia Coatings sells a product, but I think that Skyco Ospho is cheaper, and comes in gallons. Mark is dead on about preparation. But flash-rust and microrust is something that can be killed with one of these products. -Lawrence |
