Just curious...if the purpose of claying the car is to remove as much if not all of the contaminants? Then why not use the MOST aggressive clay bar all the time? I saw that Meg's has 2 different levels of clay...
Yeah. I bought the cheap Home Depot branded bottles and they were horrible. 3 out of the 4 i purchased wouldn't spray a thicker than water leather cleaner. I went back and got the Zep branded ones and they work great so far and spray quite a bit of product with just one squeeze....so far so good.
The "Zep" branded spray bottles at Home Depot seem to be pretty good also. Do not get the cheap 99¢ Home Depot branded ones. They will not spray anything at all that is any thicker than water...
