I just had all my front suspension and steering parts sand blasted and now I need to primer them before I paint them. What do I use to do so? I have a can called "Prep-All"
wipe down with wax n grease remover,prime with epoxy primer.I like southern polyurethanes black,Im doing my 56 victoria with SPI products and using H.ouse of Kolor for base n clear,
First, it's a good idea to take a scotch bright pads or steel wool and remove all the imbedded blasting media from the parts. I used plain old rubbing alcohol to wipe everything down. Then I used a small propane torch to "burn" all the moisture and whatever else is on the part. You will see the moisture go away as you torch lightly. Heat your rattle cans in hot/warm water, shake em up good and let it fly.
56 Ford. As soon as possible prime the bare sand blasted parts. Over the last 45 years I have sand blasted many many parts. I do not treat the bare metal unless the parts have been setting for some time. I will then use a metal prep like Prep & Ready a POR15 product. I have never had a problem with any sand blasted parts or car bodies ever. My old Model T that was finished in 1969 was a total blasted car, the paint is still perfect after all these years.
I have paibted the rest of the suspension with flat brown enamel first then gloss black protective enamel from rustoleum. Worked great and have no problems with it. Did my old truck aswell and held up for a long time. I would have primed them last night but ran out of the flat brown enamel last night when I primed the spindles.
I use a metal prep from NAPA to clean the bare metal of any contaminates including greasy fingerprints and the us the green etching primer that I also get at NAPA,,thy have it in rattle cans and quarts & gallons. It can sit a while but when I get ready to paint I scuff it and use a surface prep to clean and spray. HRP
Trying not to be a killjoy here, BUT........ Aren't you worried about sand being inside the joints of the idler, tie rod, etc? Or are you replacing them? Sand inside these things will kill them pretty quickly. I always diss***emble all my front end pieces before blasting, and don't do anything with a ball joint on it. Those, IF I am reusing, I carefully mask, and wire brush or manually sand. As for prep for paint, same as the others recommend, Scuff, clean with pre-paint cleaner, good primer (epoxy or etching) then a strong paint, I like catalyzed acrylic, poly or urethane.
