Tried using the lower pressure settings and dialing in the gun. Had some problems getting the base to go on without looking striped. Used 50% over lap, gun about 4″ from surface, 16 psi but as it began to flash the overlapped areas looked and stayed darker.
Backed the fluid out another 1 1/2 turns and tried again thinking it was spraying too dry but it did not seem to help that much. Bumped the pressure to 18 psi and it started to look better but now I am at the top range (if gauge is right) of the gun.Here’s the clear coat at 3 1/2 turns on the fluid, 18 psi at the gun. Added 2 oz of SPI 885 to the last coat but still ended up with some orange peel.

I have the LV cap and shot my last round of clear at 25 psi based upon some posts I had read. Really put a cloud in the air for sure.
Super! Just what I was looking for. I will be spraying some SPI MS clear today so I’ll try playing around a little with the pressure. Most guys seem to go 10 psi higher than what you are suggesting so it will be interesting to see if I can get it dialed in.
Temps here have been in the low 90s for a few weeks now. I normally paint in the morning hours so anywhere from 75 to 80 degrees.
Thanks for the help.Thanks for the replies.
I’ll sand and re-shoot it tomorrow.
Open the fluid and up the air pressure on the gun.Alright I give that a try.
I just started using the LPH400 and the instructions say that 16 psi gives me 10 at the cap. They also say to keep the fluid control set to a minimum level. This is what I was trying to accomplish.
Normally I set the fluid control 1 turn in from wide open and then adjust the psi to get the spray pattern right. Does anyone actually use the LPH400 at 16 psi?Using the slow reducer 85 degree.
I believe it’s best to use 80 to strip with but then go over everything with say 180 on a DA before proceeding with epoxy.
Some guys will go straight over the 80 with epoxy but the possibility of shrinkage causing the 80 scratches to show is a concern.I have tried three times now to submit the winning picture but I keep getting an error message. I can view the gallery photos but the submit button doesn’t like me. :S
