Salt chipping trouble

Posted by Aviator on Friday, August 5, 2005 11:12 AM

Well, I thought I was doing this wright, but I guess not. I painted the wing of my B-24 silver (Tamiya aluminum to be exact) and then proceeded with the salt chipping. This has to be where I goofed. Disapprove [V]

I put a few drops of water on the paint (after it had cured a few days, of course) and sprinkled the salt on. I let that dry for a few more days and then painted it. This is what happened. Angry [:(!]

Please tell me this will get covered up with another coat of paint. Sad [:(]

I even let it dry for a few more days after I painted it just to make sure I wasn't imagining things. It's still there. Has anyone else had this problem and how do I fix it? Black Eye [B)]

Looks like too much water to me. Also, did you use coarse or kosher salt, 'regular' salt will not work too well. Too soluable.

I'm curious - what is "salt chipping" and how is it supposed to work?

Well this is how it's supposed to work. I've had good luck with it before, though.

Suggest using distilled water. Tap water has many things in it that, after evaporation, could cause problems with paint adhesion in the areas where you still want paint. IMHO Smile [:)]

Certainly looks like the salt disolved too much & caused the staining effect. I tested the method using regular table salt on a scrap model & got similar results. Tried it again with the coarser Kosher salt & got better results. But I decided the mess it made & the unpredictable results just wasn't worth the trouble, for me at least.
