Wondering what is the best way to treat surface rust on galvanized parts. Parts such as the rocker pinch weld covers, the front and rear headliner strips, and window tracks and attachments.
All of these things are hidden and I don't care how they end up looking. Preservation is my only goal.
Thanks.......Dave

I think I'd be tempted to try electrolysis. It won't hurt the galvanized surface (unless the rust is underneath the plating), but it will remove the rust. Works well on thin parts, too. Plenty of info on this process on line.
Chemical rust removal would probably work as well - I'm just not sure about what the reaction of zinc/galvanized surfaces would be.

POR-15 will stop the rust and it's also relatively cheap. Scrub the parts with a wire brush or Scotchbrite and paint it on. Also, industrial supply stores sell a spray cold galvanizing that works remarkably well. I used this on my window tracks and hardware as well as the wiring cover plates that go along the rocker panels. After many years I have seen no sign of rust returning. Hope this helps.

x2 on the POR 15. If you can't see it, that's the best way to stop rust permanently.

Evaporust/safest rust remover then boeshield or teflon wax chain lube

The headliner tack strip appears to just have glue on it. If the retainer needs to be removed, the clips must be extracted correctly or they will be ruined. POR(Paint Over Rust) is not the best method to stop rust, removal is. Bare, non galvy metal can be etch or epoxy primed and topcoated if you run your car, and it's not afraid to be exposed to water. The tracks should be left unpainted and treated as James did. There are other coatings besides POR if one must cheat. POR and Eastwood have targeted the hobbiest with little knowledge of the industry. Local jobbers have other products one can use. There's even POR's competitor which is Master Series. Permatex has a rust treatment, Mar-Hyde has One Step. SEM, which provides professional products to the industry has corrosion treatments.

Shot the underneath of my plow truck with POR in the fall. We've had a terrible winter in N/E Ohio this year and the paint is wearing well without a trace of rust coming through. Very pleased with the product.

If you use the Evaporust on galvanized......after the Evaporust had done its job......what is left on the surface where the rust was? Galvanizing or bare metal?
Either way, if you just spray it with Boeshield afterwards, just doing that will protect it for years to come?
Thank.................Dave

Boeshield it a great product however I have found a Dupont product which is a teflon based waxed chain protectant/lube. it works better, lasts longer and is 1/3 the price. PLUS... the wax base dries to a film without gloss and isn't tacky. Designed for motorcycle chains it resists slinging off, water spray, & etc.
If it was a larger pitted area I sprayed some zinc rich cold galvanizing paint on a rag and rubbed it into the area. same thing I did to the Gas tank on a survivor.

What is the Dupont product you speak of?... D

Willing to bet it is this ^^
