The 3M Accuspray provides a quick and easy solution for those fast moving body shops. BUT they do come at a cost. With the atomizing heads being able to be replaced it adds extra cost to the gun. they can be cleaned out and used for a long time but with wear and tear they will need replacing. The gun did a good job applying the high build primer but I could of done with a 2.0 setup as this was a thick primer.
CLEANING the accuspray is very easy and i like the fact that the atomizing head is clear which allows the user to check visually that the spray gun is clean.
HOWEVER I have seen that 3M has a new pressure feed Accuspray which looks like it would be able to handle the higher viscosity primers. I will keep my eyes open for one to get a review done on it.
