I understand the trash issue in the paint! I’ve painted cars in a $100,000.00 booths when I worked at Porsche and Mercedes dealership and I’ve painted in a garage that I could barely see once the fog started rolling. The one thing I learned from both...trash comes from either off of you or your equipment. I’ve used jumper cables to aid in grounding the car to “demagnetize” the car, chains and so forth. The thing is I wasn’t doing...was grounding myself before prepping the car...you know that static you create while taping it, degreasing and then with the tack rag. Alot of times trash comes off the paper while painting especially on base coats, newspaper is great for cleaning windows but not for masking cars. The overspray will build up and fly off on the next coat or worse in the clear. Anyway, just take steps to make sure you, the car and your equipment ( gun, hose, booth) are clean. You’ll still experience some issues but every little bit adds up to a better job.
Keeps us up to date and the car is looking great!!!
