Auto body repair & detailing: Paint, lacquer paint, wet coats

Question
Hi
I have an old car that I recently hired a neighbours 16 year old to paint.
He did an OK job but on close inspection it seems to be textured-lots of little bumps.He said it was because his sprayer nozzle wasnt working.
The problem is it looks OK but it tends to collect dust and it gets dirty fast(it is white).
He didnt put clear coat on it so I am wondering if it can be fixed? For instance if I got a buffer with a coarse? buffer? Or would that ruin it.It is a gloss paint.Maybe after I could hand bomb some clear finish on it? What do you think?

Answer
Hello Barry! I wouldn't bomb can any clear on the car. The panels are too large for that approach, and you will probably end up with the same problem. Buffing should help the problem. Ask him how many coats of paint he put on, and if he put on at least 3 full wet coats, you could do a sand and buff job. It's a lot more work, however. First, sand one panel in a low, inconspicuous area with 1500 wet or dry sandpaper. Power buff with 3M medium duty rubbing compound, or 3m heavy duty compound if the finish is Lacquer paint. Buff the spot, and see if you really can handle this task. It's a lot of elbow grease to hand rub a car, especially one that has been painted for more than a couple of days. If it's more than you can handle, just power buff the car without sanding. Use a wool bonnet. Follow the compound up with 3m finesse-it swirl mark remover, followed by a good hand waxing. I gotta say, you are in for a big job. Maybe the kid who painted itwill help, or know how to buff. If he is going to create problems like this, he needs to learn to correct them. Especially before going ahead and painting an entire car with malfunctioning equipment. My guess is, he used reducer of a temperature range that was too cold for the paint conditions, resulting in dry overspray. Inexperience. Bill
