I am cleaning the whole truck, removing rust etc, not sure if I can get all of the rust out, but can I clean with phosphoric acid, use eastwood rust convertor and rust encapsulator, then SPI primer, Eastwood chasis black.
Will this combination. Please advise and apprecaited so much

I would skip the phosphoric acid. It's just too messy,toxic and requires a lot of water to neutralize. Go right to the rust encapsulator and chassis black.You can skip the primer if you want.The chassis black goes on pretty thick unless you dilute it following Eastwoods instructions. You may get flash rust before coating if you try to do too much area at a time.

I would give the encapsularer plenty of time to dry. | | | | | Joined: Oct 2007 Posts: 388 Shop Shark | | Shop Shark Joined: Oct 2007 Posts: 388 | Thanks for that update, so verdict is stay away from phosphoric acid.
Thanks for the tip

Ganesh well, more like stay away from that combination, phosphoric acid is excellent for the right purpose, and not toxic, especially compared to the lacquer thinner, mineral spirits or acetone you'll use to thin the paint or clean it up  Bill | | | | | | ZooKeeper Unregistered | | ZooKeeper Unregistered | well, more like stay away from that combination, phosphoric acid is excellent for the right purpose, and not toxic, especially compared to the lacquer thinner, mineral spirits or acetone you'll use to thin the paint or clean it up Bill Not only is phosphoric acid not toxic but it is in just about every soda made. | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | Well, I consider any chemical that has the potential in high concentration such as a Phosphoric Acid wash to be a health risk. Here is the MSDS which I trust to be more accurate. http://www.sciencelab.com/msds.php?msdsId=9927393Just my added 2 cents.

I much prefer things that don't produce hazardous fumes when used properly, and are easily neutralized with water like phospho
