They love my work and also love that I do your restore for 10 bucks instead of 30-50 ;) no need to try and make me look stupid a loophole/shortcut is what helps people actually get more done faster... But on something's shortcuts would have to be a no no like waxing or paint repair
Best thing I do is once a week I clean my "black thing" with a qtip inside and out and dry it where it touches the glass with a mf towel and I keep my touch up bottle behind the seat because I have to clean the outside of the window atleast once a day so most times I just do it when I'm outside...
