This isn't the most technical question, but the guy I bought my Rx7 from parked next to a sprinkler and never washed the car again or something. Almost the entire drivers side has light water spots. Hell, even the mirror has water spots. And it doesn't come of with washing. Wax sort of hides it, but it just comes back when the wax dries out. I've tried TR3, and it sort of worked, but required immense amounts of elbow grease, and it only worked on a few spots.

Anyone have any suggestions?

 

i used an orbital for waxing. took griots garage machine polish 4 and it cleaned up my water spots.

 

I have a bosch 6" random orbit type sander with a buffing cloth, would I risk melting the clearcoat off with that?

Sorry dumb questions, not the body work type of guy.

 

when getting water spots off you should first get the calcium build up off the paint before buffing.

you can do this by mixing 1 part vinegar to 4 parts of water and basically washing the car several times with the solution and rubbing it in like you would with polishing compound. after you get the majority off then you can go over it with a buffer and polishing compound or wax.

vinegar breaks down calcium so it is a little trick to getting water spots off of anything.

if you start with a buffer eventually you will kill the paint, do it right.

 

Thank you sir! Vinegar is cheap too

 

If that's your Blaze Red S5 TII in your avatar, the factory finish was single stage. Of course if it's been repainted, you may have a clearcoat finish now.

I agree that white vinegar is great at removing any kind of mineral deposits from car finishes. I also used to quite like Mother's Paint Cleaner (not the Cleaner and Polish, though that is also a nice product) for removing the light oxidation that seemed to appear almost overnight in my original factory Blaze Red paint. I never tried applying this product with a buffer; it works fine by hand. Finish with the carnauba wax of your choice, and you're set.
