elcamino/wheelhorse 9,362 #3 Posted August 15, 2015 that looks like the stuff, I am very impressed on how go it works. At $50.00 a gallon it is hard to get any free samples from the brother. Share this post Link to post Share on other sites
DennisThornton 4,771 #4 Posted August 15, 2015 Ospho is a "metal prep" that is phosphoric acid based. Good idea to use a metal prep before priming!

953 nut 62,476 #7 Posted August 16, 2015 I have always sanded off the black residue left by the Ospho and then used a self-etching primer. Have done this on lots of street rods with great success. Share this post Link to post Share on other sites
