White "spots"/corrosion/oxidation of Miata latches and screws???

Chuck

I have been in DeLand, FL for over a year with my 03 and have seen no corrosion problems (yet!). I have seen the same "salt air" corrosion on aluminum window frames, though.

Naval Jelly is a powerful rust REMOVER. It is very acidic. I would not recommend it to PREVENT corrosion, especially on zinc based castings like Miata latches.

It is more than a rust remover. There are various types sold under the trade name. It's made for more than just Steel & Iron. The basic gell is for ferrous metals. You can also use several other preperations of milder strength. The idea is to remove or neutralize whatever is causing the powdering. Florida has a common problem with salt in the air. Acidic solutions neutralize salts.

The best long term solution is to microgrit blast parts, and refinish with a baked on finish (Powder coat?)

My 99 has quite a bit of time in SW Florida, and was often parked a hundred feet from the gulf. I haven't had any problems. On the other hand, several late 80's GM cars had problems with door window frames corroding from the inside out. One key practice is to frequently wash and dry a car, and flush the underside as part of the wash.
