Question for the Experienced Body and Paint Guys

I would spray the bottom sides then tapes them off. Put them back on then spray the whole car. Its hard to get everything to match even with base coat, single stage metallic is even harder. I know guys who spray them all apart & are very good at it. You have to have everything just right. The area you spray has to be the same temp, same air pressure at the gun, same amount coats ect. Ive tried it many time & i cant do it. Ive been spraying for 20 plus years. I pisses me off that i cant lol
