I haven't been able to wash my car in a while and it's been 6 months since I last waxed it. I have some free time today so I went out to give it a good cleaning. However, I discovered a ton, and I mean a ton of small tar spots everywhere. I've been out there with the clay bar for over an hour now and i'm only half way done the hood. Even the windshield has a ton of these spots. I'm killing my arms trying to get these things off, is there any product or easier way to get this crap off without my arms falling off???
