Disclaimer: I have don't my share of body and paint work, and typically would just have this blasted, but I don't really want to deal with all the sand mess and I don't want to blast the whole thing.

My 65 double cab had the inside upper cab walls and dash sandblasted by a previous owner and then it sat for a good amount of time. It has a good amount of surface rust, the flat areas clean up pretty well with a roloc scotch pad on a angle die grinder, but all the nooks and crannies, as well as the fuel tank area are going to be impossible to clean this way.

I'm looking at thishttp://www.eastwood.com/review/product/list/id/4967/category/234/?p=3 to kill the rust, then coat with a good primer sealer before paint. The reviews seem to be excelent. I have used naval jelly plenty of times, but I don't want to wash it down with water and flash rust again.

Anyone used this stuff with luck? Any other methods I should be looking at?

I have never used that product, but it looks like its just Phosphoric acid, available at half the price at Home Depot

I sprayed some panels about a year ago and they are still clean but it probably is just straight phosphoric acid.

You don't have to meticulously clean off the acid before spraying it with primer. Any primer sticks to it like glue.

Thanks, I actually was cleaning out my flammables cabinet and have about a pint of the fast etch, it came in a motorcycle tank seal kit I bought years ago and I forgot all about it. Going to give it a shot sometime this week.

Just get a small hobby sandblaster, they are about $20 to $30,use it for the nooks and crannies.
