Started messing with 2 step gun today. Im still waiting for the right size tip to come in so the first truck I did I just low pressured both steps. The results were horrible, I ended up brushing the entire truck.
For the green truck I used my jrod with a 2515 tip. I was able to apply the soap at a higher pressure and had better results.
I also took a second and washed my pickup. It ended up still having a film on it afterwards.
The black Pete has been sitting for 2 months so I’m sure the dirt was baked on. The green pete was washed/brushed a week ago. My pickup was washed 2 weeks ago.
I’m using counterpunch and panda mixed 50/50 with distilled water before downstreaming with a 20% gp on a 5.5 gpm machine.
I’m trying to figure out if my results are from wash frequency, soap ratio, or application pressure.
As far as the film, when was the last time it was washed? Counterpunch and Panda damn near needs weekly washes as the soaps are just weak compares to the non-polish safe soaps. As far as ratio I just open up my 2 step gun all the way, so I’m drawing at 20:1 I believe (would have to verify this though).
The truck it self doesn’t seem to be polished, tanks look dull but the rims look polished. If thats the case you’ll need what you have which is counter punch and panda at 20:1 or lower.
Did you do a ratio test to see what your machine is drawing.
How often do you wash them ?
Whats your pressure?
You should be laying down soap at 1000 to 1500 psi and rinsing at 2300 to 2600 psi.
And remember like @GeorgeNicholson said 9 times out of 10 you’ll have to brush the first time with cp and panda. Its a very week soap. Now HF and grizzly is a whole other ball game but you cant use that on polished aluminum.
Just make sure you save me one of those nice expensive rigs to wash.
