Does Bondo go onto the bare metal or can you paint it with POR15 and apply the Bondo over the Paint?

Also I painted a large area of a Friends Car with Restoleum Spray Paint (Gray) and within 1 year the paint faded (my Friend never waxed it). Also the paint does not appear to dry as hard as paint made for the Job.

If you use a Spray Gun with an Air Compressor be sure to use something to filter the moisture out of the compressed air to the spray gun (Harbor Freight has them as well a spray guns).

Nothing spoils a paint job like a big blob of water mixed paint!
