fish eyes mess

[larry harding]

i am restoring a king midget, all new sheet metal. some of the new parts have sat for several months and have surface rust. i used Rust Blast and did a good job of removing the rust. i flushed with water as per instructions. i first tried nason self etch primer, then nason ful poxy primer. i got fish eyes, streaking and just a messy look. i will probably have to sand or sand blast to get  the primer off. i was hoping to avoid sand blasting with the RustBlast product. i'm no pro painter but have painted cars , motorcycles etc. several times over the years and never had problems like this.  should there be another step between Rust Blast and priming that i'm missing, or wll regular paint materials just not work with Rust Blast?

Fish-eyes are usually caused by contamination of some sort.  Did you use the KBS Klean on your new sheet metal to remove all of the manufacturing residue before you applied the RustBlast? Please let us know and we can assist you further and get to the bottom of this as RustBlast should not cause your primer to fish-eye.

the directions said not to use cleaners that would keep rust blast from working properly, so i put it on the bare metal, there may have been an oil prectorant on it. i suppose i must now strip back to bare metal and start over . would you suggest blasting, sanding or using a good paint stripper?

The RustBlast Directions state the following: "Surface to be treated should be free of dirt, oil, grease and other contaminants. The cleaner the surface, the more effective RustBlast will work." At this point, you could sand down the surface with 300 grit, clean the surface with a good water based cleaner (like KBS Klean) and then apply more of your primer. Please let us know how that works for you.
