Looking for info from anyone that's painted the rear face of a galvanized chassis after the vehicle has been assembled. Any tips? The galvy shine looks odd with the white truck.
PPG DX579 metal cleaner, then DX520 Metal conditioner. Google them up for proper application and usage.
I used them when I painted both side frames on my 110. Going on 4 years now and the paint is still perfect.
Just looks odd with white, but I agree it looks better once it dulls downI agree the shiny galvy is ugly. Im not going to paint mine but hope that vinegar washes will bring some patina to the rear cross face.
Im going to do it here since it's sort of an odd job. If I screw it up, I'll have a shop do itThere are many options depending on the paint system used. Are you doing this yourself or having a shop do it? Any competent shop should be able to coat galvanized metal properly with your desired finish.
There are greatly varying levels of DIY in painting. Are you looking for the best job you can get from a can, or from a gun? Do you have access to a spray booth, equipment, PPE, spray gun experience? Isocyanate and VOC exposure is no joke.Im going to do it here since it's sort of an odd job. If I screw it up, I'll have a shop do it
Their polyurethane system prescribes an alkyd primer which will chemically react with galvanizing and peel. Their two epoxy systems, like nearly all etching epoxies, are compatible with galvanizing. All their systems involve 2-3 coats total of primer and topcoat.I am going to do the same with my galvanized chassis this winter. I have been planning to use Steel-It paint as I thought I read it could be sprayed right over galvanized metal but I need to confirm that.
I had about a 10 hour window in 70 degree weather with the epoxy primer. Went on well, nice coats. I even botched a top coat and removed with paint prep and another solvent and the primer held up extremely well. Great stuff.Another note on the 2k SprayMax products.. Being an internally-mixed single-use product, it's best to have every piece you'd like to finish prepped and ready to paint. If you have other brackets and parts that need painted, do them all at one. Once the can is mixed, the pot-life countdown begins.
