No, they are all the same
Not sure i understand ya. Can you come again?
I wouldnt know what to do without mine, speeds up the repair process remarkably which results in more through put. I use mine to cure clear,base,sealer,primer and even filler.
I would be more comfortable using a final wipe solvent instead of Wax and Grease remover.
Every color needs to be blended into adjacent panels for an exact match, even solid black in some cases. I have had solid blacks with 6 different varients. Only bumpers are panel painted but they never match 99% of the time.
:welc You came to the right place
I have had AG40 pop on me a couple of times. My suggestion would be the same as others have stated and stick with the 2021 if thats what your used to.
Be carefull, the stuff does like to pop very easily as is…
The more you paint the better you will get at estimating how much you will need, just another thing that comes with experience. Try estimating more than you think you will need and just charge for it. Last thing you want is to run out while spraying.
