for the body guys
OK..because i will be doing the metal work over a period of time i decided to try Eeastwood Fast
Etch to get any rust the 80 grit didn't and prevent any flash rusting over the next while (hey,i'm old and in no hurry).
I made the mistake of leaving too much product on and it dried with a heavy rust protecting grey film.It will have to be sanded off,which i was going to do anyway or reapplied and dried more thoroughly before cleaning with acetone and priming.
To it's credit it is an excellent rust remover and should protect the bare metal indefinately inside my shop.Just don't leave it too wet if you use this product!
