my way of thinking is if i can use a 40 for everything instead of a having multiple rolls of each shade like my 35 i buy the 40 so i can cut doubles out than to have a 24" for side windows and a 36 for back glass
never let the customer watch. always double check your work for water pockets or bubbles before it leaves. always ask the redneck to wash the mud off before bringing it in. I get that alot...hey man can you tint my windows this weekend sure and they drop it off looking like it just came from the mudbog and then bitch when theres a few pieces of contamination in it im like look at all that mud in the gaskets after i done washed them twice.
