Hey guys, I parked outside of this house and as I was leaving there were massive water spots all over my car (sprinklers). The car was left out in the sun for about 8 hours so it really had time to bake in the 100+ degree heat. I tried polishing these water spots out using a 5 inch yellow LC, 3m compound, SIP and 3MUF and still no luck. I even had the rotary up to 1700-1800rpms at one point. Are there any other compounds out there that will do the trick? Im afraid of burning through the clearcoat.

WOW! I just had the exact same problem. It only sat in the sun for a few hours as well before I got it off and they were etched into my hood so bad. I tried everything from OP to SIP, even with my rotary and foamed wool/105 combo. I finally broke out the PC and an orange 5.5 low profile light cutting pad with Meguiars 105 to just to attempt something different, and it cut through the badly etched water spots quickly within two passes. I couldn't believe how well 105 worked with the PC and a light cut 5.5 inch pad. Definately try this combo, but next up would be wetsanding. I also should mention that it broke down practically LSP ready on my dark green paint.
 
damn thats all it takes for water spots to bake?

is rain and water sprinkers different? because i had rain on my car and it sat there for days in 93 degrees weather and it didn't do that...



damn let us know how it works and post some after pics
 
Water sprinlers will, the majority of the time, have either hard tap water which will leave minerals behind, a water enriched with some sort of fertilizer, or a combination of the two, which both will causing etching on the paint if left alone for a bit. Rain water typically won't etch paint unless it is left for an extremely long period of time or the rain is acidic in some way.
 
Sorry for the thread hi-jack, but good to see another fellow Kentuckian on here.



I'd try the #95 first, then the #105 like tunerman suggested.

Have you tried 4" pads on the PC or distilled vinegar? If all else fails, I would just wetsand it with Meg's 3k Unigrit. Good luck!

Vinegar is a good option. Try it and remove the remainder using the rotary. If that's not enough, wetsand with Megs unigrit 3000.
 
hmmm it looks like Ill give the vinegar method a try and if that doesnt work Ill bust out the udm with 4 inch pads and some 3m compound. What I dont get is how can the PC correct more than a rotary with slower speeds?? I mean dont the head honchos use rotaries in the first place since it corrects faster and leaves a much better finish?? I know it has something to do with "chasing" the defect but if someone has a better explanation Id love to hear why. Thanks you guys.
