Well it's been about 2 weeks since I have washed my car, and during that time there has been a mix of rainy and stormy days along with hotter and sunny days that my car has been exposed to. At the moment my car sits outside 24/7, which sucks, so it gets exposed to a lot. I happened to notice earlier in the week on my hood that there was dried on water from the rain that almost looked whiteish like calcimum deposits in a way. I didn't think too much of it since it was not hot out after it got rained on, nor was it in direct sunlight. Plus, it has been rained on before and had this apearance after getting rained on, and I have never had any trouble washing it off before. Well that was earlier in the week, so today I tried using some QD to get some of it off. Now some of these areas have left a faint white mark outlining where the water dried on when looking at certain angles.
Needless to say I am pissed, stupid me for not getting this crap off earlier with at least a QD. I tried using vinegar, clay, Poorboys Carnuba Polish by hand, no luck, these aren't coming out by hand. Guess I'll be spending my weekend trying to get this crap off with the DA.
I could see this happening from hard water or tap water getting sprayed all over it and left to dry in direct sunlight, but from rain water drying on it on cloudy days? I don't get it. Are darker colors vehicles more succeptable to this than others?
The last time I fully detailed my car was the middle of April with Poorboys Carnuba Blue Polish topped with two layers of Polycharged Collinite 845. I always though that Collinite 845 was supposed to be one of the more durable waxes out there, and should have provided some of the better protection against water spotting and etching? I don't get it, should this be happening with 845 on darker vehicles, or is there another LSP that provides better resistance than 845? Anything else I can try before resorting to the orange pad and cutting polish?
