Auto Painting Use

Can you use this on a car after you have sanded down the paint just before you prime to get the paint to adhere better?
Asked by: NickyD
This stuff is great to get rid of rust. Scuff it with a wire wheel/wire brush or sandpaper and spray on let it sit--rust goes away, rinse and prime.

I used the solution on 3/8 " steel plate that was particularly marked with scale and the low-strength phosphoric acid in the Prep and Etch created an attractively refined-raw skin

Used recently and followed directions letting it dry overnight to black. The instructions are VERY vague where it says to whip with damp rag the following day. When I wiped down it left and powdery film and the rust came back in some spots. Other phosphoric acid products say you can just paint without cleaning anything. Some people online try to neutralize the acid with baking soda and water when wiping down. Called their customer service line for more assistance and basically their help line is worthless. It almost sounds like they have no clue about their own product, have no added tips on the very small / vague instructions. That was a waste of time. I will be buying Ospho in the future as they say you don't have to wash the black off at all, just paint.

I had light rust on my drill press table and also my bandsaw table. I applied the product, waited a few minutes and cleaned it off. Looked good. Then I remembered that the instructions said to let it dry overnight to fully neutralize the rust. I applied another coat and checked it the following morning. the tables were covered with a rough, black coating that resisted removal. I called the manufacturer help line to see if there was a recommended solvent and was told it was my fault for applying a second coat, which "burned it in." I would have to sand it off. Bummer. Then I remembered a couple of smaller items that I had applied one coat to and let sit overnight. Same problem. I think the manufacturer needs to consider the possibility that their instructions are not right.

Rated 5 out of 5 by from Great for metal prep I'm really happy with this product for my truck restoration!! It's great for surface rust that's imbedded and can't be grinded out. Really makes me confident that I won't have rust under bodywork and paint. Great prep for sandblasted metal before epoxy primer Much cheaper than auto paint supply store metal etch/prep and does the same thing

Rated 5 out of 5 by from Best Metal Etch anywhere....Period! This metal etch is by far, the best etching solution I have ever tried. I am an automotive restorer of classic muscle cars and this product blows POR-15's "Metal Ready" away as well as any other restoration suppliers metal etch which usually costs 2 - 3 times as much. It is fast and aggressive yet not destructive. I made a dip tank from one of HD's large 27 gallon plastic totes and filled it half way with 14 gallons of this product. Then I submerged 2 big block Chevy cylinder heads in it for 24 hours after they were sandblasted but had flash rusted. When I pulled them out and rinsed them off, I was amazed. Rust was gone and a nice dark phosphate coating remains after rinsing. I never thought of HD for restoration supplies but lately with this product and some of there Zep brand degreasers, my thoughts have changed. Home Depot...Please do not stop carrying this product!!! The price is great and so are the results. I'm loving it!!!

Rated 5 out of 5 by from Great Thin-Set Remover I bought this product to try and remove hardened (5 years) thin-set from the back of tiles I removed. I had to let them soak for 24hours but the cleaner worked to eat away the thinset and saved me from having to retile the entire floor or finding a similar tile. This product was a life saver for thinset removal.

Rated 5 out of 5 by from This stuff works very very well! I used this stuff to clean a steel gas tank that had rust in it. I let it sit in there for 3 days and then it was like brand new again. I'd highly recommend it for an application like this.
