I wish i could find the post i searched maybe 15-30 min before giving up and making this post, right now i use lights from the garages i work in, along with the sun, and I can make the paint look maybe 85-95% swirl free but that last part is hard to see and correct. People love my work but I still don't think Im at autopia perfection until there is not 1 swirl mark on the car!
