I'm trying to clean my A-arms and front cross member so I can paint them. My question is how do I get into those small crevaces? There is a plate welded over the channel making it impossible to sandblast in there. I was thinking of taking it to my plater and having them dip the pieces in acid. What can you guys suggest?

I did what I could with the sandblaster and put a heavy coat of paint on mine in the recesses.....

Acid dipping might be OK, but since I have no place local to do it, it was out of the question for me....
