underground. state your opinion without quoting people .
when trying to lay clear slick with a gun that does not atomize very well you can get excessive build. which can lead to pop and even delamination. just about every thread dealing with pop comes back to a cheaper gun and production clear applied too thick too fast. if you think your going to do this often and especially if you have any thoughts of doing it for a living get equipment that will help you and also save money. a cloud in the booth is money going up the stack.
