man well done! that's one hell of alot of work for a clit, to stop the dust and overspray settling do you not leave the ventilation fans running in the paint cabin whilst drying?
ventilation fans are stopped after few minutes.. we need to stop because we have to apply heat for some time.. but specific to this laquer case (as I'm afraid of that it can flow at higher temperatures) we apply only 20 minutes.. and then the car stayed in the cabin until next day morning.. I always prefer to take appointment for the last car painted, otherwise you can never guess what will happen when you take a freshly painted car outside..
car now is initially sanded (morning) , waited another day under sun and polished night time.. dusts ( a few) are removed..
now will wait for 10-15 days for the paint to loose its gloss which means surface hardened and dried completely then will be polished again..
