My car was sandblasted to bare metal inside and out. I used Eastwood After Blast.....supposed to be a cleaner and also etches with phosphoric acid. Will be priming with an epoxy primer.
The problem is now there is a chalky white residue in many areas that has to be scuffed off. This is going to be a much larger time committment than I anticipated. http://www.eastwood.com/eastwood-afterblast.html According to Eastwood, I should be able to prime without any further prep, but obviously this will not work. Any suggestions about removing the residue and prepping for primer? (IMG:http://www.914world.com/bbs2/uploads_offsite/i75.photobucket.com-18986-1483802178.1.jpg) |

From what i understand the acid needs to be neutralized because some paints wont stick to it. Not to mention the physical barrier the powder probably makes on the metal. Phosphoric acid is the same as Ospho brand which you will find alot of info about on line.
