metal cleaning prep for paint . what should i use ?

[rav440]

once i get the patch panels welded in the firewall and the udercoating off of the inner fender area , what should i clean the metal with to get it ready for paint ?

i used AIRCRAFT stripper in some areas of the engine bay and alot of it plus KEROSENE & PAINT THINNER/MINERIL SPARITS for the under coating on the inner fenders .

i want to be sure im on bare metal before primming & paint  . so what steps & products should i take and use  to clean the metal ?

thanks RANDY

You could use mineral spirits but you have to wipe it off with a dry rag because if you leave it on it can cause fish eyes. PPG also makes a cleaner called DX 330, but mineral spirits will work and be cheaper

Mineral Spirits will cause fisheye.....Then you'll really be cleaning.  They make products like....and I think this is what it's called.....called prep-all....or something like that.   If it's bare metal...I usually just use lacquer thinner.  If it's prepped, and ready for paint, I'd use the Prep-all  (or whatever it's called....or some product of equal usage)  then go over it with a tack cloth.   In fact...Wal-Mart has that prep stuff in the automotive department.   Maybe the experts can reply to this one???

Solvent based prepaint surface cleaner....AKA prep-sol ...dx-330 or 440...GON ...m-600 the list goes on. Just be sure its a solvent based cleaner,and that you dry it off with a clean rag as you go(dont let it dry on its own)and it will work fine.
