I am wondering if anyone has ever compared these 2 products against one another and can give opinions or pros/cons? They both are virtually set out to do the same job dissolve rust to a certain point with phosphoric acid, turn hard to get rust in pits to iron phosphate, and leave behind a layer of zinc phosphate. I have used Eastwood fast etch and was pleased with the results and feel it did what it was supposed to do. Anyhow I used it all up and want to get more but just wanted to make sure that there isn't something even better out there. I like a lot of what I have read about the Picklex but have a few questions for those who have used it.
1. It says not to use chemicals/cleaners over the picklex but a damp cloth. What about wax and grease remover before paint?
2. It also talks about only a small amount of picklex is needed to create a thin layer on the metal. Where as the Eastwood fast etch you're suppose to keep wet for about 30 minutes. To me that seems like it gives it more time to dissolve the rust and convert the rust in the pits. A situation I deal with often is beads on the edge of fenders where the sheet metal is rolled around a wire. I like to let the acid soak in there for awhile to do as much good as possible where I'm afraid the Picklex might not do as well since its not intended to work in that manner, at least it sounds that way from what I've read.
Any thoughts/comments?
TIA
