slo929 Posted October 10, 2012 Share Posted October 10, 2012 (edited) Hi all, Well i pulled the old 240 out a couple of weeks ago after not working on it since March of 2009 and got the thing fired up. I was planning on just selling it, but after replacing the front wheel studs and throwing on the set of Rota's i bought a while back i am infected again with the Z virus and back to finishing the thing... so here is the question i have for you all, when i put her away she was mostly down to bare metal. Being in New Mexico, we have no humidity so rust doesnt occur as it does elsewhere but a few spots of surface rust did appear. I have thoroughly resanded the areas but i can't seem to get it out of some of the scratches that were left behind from when i removed all the paint. I was wondering if there was some sort of wipe i could use to prep the areas or if i need to get out a angle grinder with a flap disk and potentially maul the metal. It really is tiny if not microscopic spots, but I dont want all the work i have behind me (and in front of me) to be for nothing. thanks for the help and i will post some picks in a little bit. thanks again!

Leon Posted October 10, 2012 Share Posted October 10, 2012 OSPHO or Naval Jelly should take care of it. Quote Link to comment Share on other sites More sharing options...
slo929 Posted October 11, 2012 Author Share Posted October 11, 2012 Thanks i look for it! I also got ahold of a friend who paints for a living and he suggested a red scotch brite pad with lacquer thinner to get stubborn rust out of small scratches. Anyone ever try this?

Tony D Posted October 11, 2012 Share Posted October 11, 2012 (edited) I have a second vote for OSPHO, on a red scotchbrite pad. THEN you can use red scotchbrite and lacquer thinner. Lacquer thinner will never get corrosion in scratches, OSPHO will leave truly bare metal with no corrosion. I prefer it over naval jelly which will also work, but IMO OSPHO cleans off easier/better. Good Luck! *Edit* Well, the three part series by my friend Pete... It's a nice idea, that Vinegar Water. I'll still ike OSPHO or going with dilute Phosphoric/Hydrochloric Acid. The difference between that Vinegar-Rust Conversion and OSPHO/Dilute HCL is that all the metal is that "clean sterilized white" color, there won't be any of that black "converted rust"... That is a nice series of videos, but I was a bit turned off at the negative marketing. I don't know how they do it in Texas, but using OSPHO is pretty standard stuff, I can't think of a shop that doesn't do it. So maybe it's a regional warning.

Pharaohabq Posted October 12, 2012 Share Posted October 12, 2012 Hey Slo, I thought you sold that Z. I hadnt seen it for a long time. Always locked away I guess. I would love to help if you need it. I have the body work on my 280 to do... Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted October 30, 2012 Share Posted October 30, 2012 I use 'Rust-Mort' made by SEM...it's main active ingrediant is phosphoric acid that sets in the rust and eats it but doesnt damage the steel. Clean with laquer thinner, and then apply an epoxy primer directly to the metal. Ive got about a dozen classics including my own Z with no problems of rust returning in the last 10 yrs. On my facebook, there was several photos of the bodywork on my 76 if u wanna check it out. Facebook.com/classickustomsgarage Quote Link to comment Share on other sites More sharing options...
