Excessive overspray should not be an issue. If you have lots of overspray you need to adjust your gun correctly and your air pressure. You should tack between coats of base though, to remove any oversoray that may be on the surface.Question about blending over spray.
Since I'll be blending the base coat on a horizontal surface, I anticipate a lot of dry over spray on the rest of the hood. How do I deal with this prior to clearing?
The 23psi is just to get the 10psi at the air cap that's required by the EPA. You can go higher to meet your spraying style. Most people do bump it up several pounds.I'm using a DeVilbis Finish Line, not a 2, 3 or 4, but the original FLG with a #3 HVLP air cap and a 1.3 tip and I'm spraying at 22 psi with the trigger pulled. DeVilbis states that 23psi is the maximum but 22 seems to work best. For the last coat of base I've reduced the pressure to 18 and pulled the gun back. I'm also using it for clear.
Tomorrow, I'll check the reducer that the paint jobber gave me with the Wanda base and let you know what it is. It's not SPI
Use the SPI all that other stuff is good for is cleaning your gun. It's the low end stuff that I hate and causes people issues. You will notice a difference I promise.The paint supplier sold me Collision Pro reducer and I have used it in all the base I've applied to the car.
I also have SPI Urethane Reducer.
AAE. Thanks for that information. I did not know that. I'll have to try that when I spray the clear.
