Question for the P&P guys about high build primer
So I am about to start spraying the high build after doing the body work, filling and etch primer. The directions say mix 4:1 for high build and 2:1
for surfacer. I tried a little test spray and the mix seems awfully thick. It barely goes through the gun, and dries really dusty. It is thick though.
Is this typical for hb primer. I am using a star gun with a 2mm tip and spray pressure about 300 kPa. I have done a lot of airbrushing in the past
with acrylics but I have never used high build auto acrylics before. What's the go with this stuff?

It will be very thick at 2:1. You will need a 2.5mm tip to feed putty. To do it with a 2.0 or 1.8 tip you will need to thin it to primer surfacer.

Yeah I thought I would prob need a spray putty gun. The mix ratio is 4: 1 for high build and 2:1 for the surfacer. The etch primer was mixed at 2:1
and it sprayed well. I might just build up the surfacer with a few extra coats?
