Now that I've taken my Z out of storage and handled all mechanical chores, tackling cosmetic. Car is an 03 w/ 13,500 miles on it now, I know the previous owner live around cape cod and despite the low miles shows in certain aspects - dried out rubber door and trunk seals/gaskets & oxidized exposed aluminum parts.

What recommendation do you all have to remedy these 2 issues? I've heard 303 aerospace is good but I thought that's more for vinyl, how about to bring so,e life back to oxidized al parts like control arms throttle body even alternator housing?

I had the front end clay barred/waxed and has xpel film installed, I'll be clay barring and waxing the rest of the car this weekend as well.

Subscribing ...

I have an 03z as well with 11k miles. Car lives in a garage, but I'm getting white oxidation spots under the car as well as my aluminum motor parts seem to be getting a "rust" colored tone to them faintly.

Would love to hear suggestions

Yes I also have "rust" on joint welds - not rusting per se, like I'm not concerned about it structurally, but it just doesn't look pretty. You'd have to really look for that though, also have rust on the bolts that hold the seats down, but no other bolts on the car have rust oddly, no evidence of water ever being in the car I'm assuming its just humidity and salt air and age.

Nobody has an answer for this? I guess I'll check out autogeek

are the cars parked in temperature controlled garage? If not than oxidation is part of life, especially if you don't drive the car enough so it can be exposed to various temp changes. Aluminum doesn't rust but it will form an oxidation film.

Excellent question!

Doesn't GM sell a gasket/seal preservative ( maybe silicone based) for seals?
