Just ordered the porter cable from the Geek. I have what looks like some hard water stains on the roof and trunk, most people dont see em' but I do. What type cleaner would you use with the machine on these thingys ? Always did my car by hand so I'm alittle apprehensive with a new machine. I've already put a clay bar to it.

thanks

What was that, Pinnacle XMT360 you say ?
I'll give it a try.

For the love of God, man, don't use that stuff, whatever you do!!!







Just kidding. XMT360 should work just fine. Start out working a small section, spread the polish on speed 3, crank her up to 5 or 6 and work the polish until it looks almost gone. Wipe off with a clean towel and go from there. Don't forget Vette paint is rock hard so it may take some time to fully remove the water spots.

There are lots of polishes that will work. It's a good idea to find the one that is the least aggressive that still gives you results.

On vette clearcoat, I like Menzerna Intensive Polish. IF you don't want to wait for a mail order, go out to your local NAPA and get some 3M #39002 instead. Both are good polishes, and should remove your waterspot etching very quickly by PC. Use an orange pad - that vette clearcoat really is hard.

You can try less aggressive approaches --- it depends upon how long those spots have been allowed to "bake in" in the sun.

I highly suggest the Menzerna Nano-polish. It truly is designed as a finishing polish for ceramclear finishes so it has a little more bite initially but breaks down nicer than any polish to date on corvettes hard clear. Remember these stains are likely etchings from hard water and acid rain so in the clear, not above it.

Thanks for the tips:
but the Bugman hit it on the head, i can't wait for a mail order now that i have the PC so i'll pick up the 3M

thanks again

As always, try a limited area first - spend 1 hour just perfecting a 2' X 2' area on your hood. This way, you'll easily be able to compare your test area to the rest of the hood that you haven't touched yet, and you'll be able to see your progress in small steps.

Don't make the mistake of trying to do the entire hood at once. You'll convince yourself that you're having no effect at all , then you'll quit!

killrwheels' comment is right on : you need to know that your clearcoat is pitted, so you're not washing a stain off the surface, you're grinding the surface down to meet the bottom of the etched holes in your clearcoat.
Good luck !

Please keep us posted on your efforts.

Some water spots can be very deep and even with a rotary w/ black heavy cut wool its hard to get everything out.

i haven't had a chance to pick up the 3M product
yet, but i will try to get some before pics up this afternoon.

I like Adam's polish and a Sonus polishing pad on a speed of about 2-3 on th PC

If you are attempting to remove or reduce defects, you need to run the PC at 5.5-6.

Start at by spreading the product in a 2x2' section with the PC off, then turn on the PC at 3.5-4 and work the product in a bit.

Then turn it up to 5.5-6, move slow 1" per second and apply some downward pressure to the head of the PC. Work untill the product starts to turn clear on the surface.

Wipe the remainder of the product away with a good MF. Check your work, repeat if needed or move on to the next section.

Remember corvette clear is very hard and will take some time to do correction with a PC.

finally took some before pics, doesn't really get em though
