Question for body guys here about paint..

Yeah..there are a few guys i watch on youtube that paint.. one yells at the camera which is annoying but has been doing it like 40 years and gives good advice
My friend Pete is awesome I love the cussing and swearing but realize I'm a weirdo...I've also spent time(20 plus years) in the auto business and the cussing just goes along with it...you come to hate people and you get to where you just don't want to hear about their car troubles and you say "bring it by the shop..." that shuts 'em up cause then they realize they rent getting it for free...:)
