With HS clears overlap is really important as well. I've found that for me 75% works best. Less fluid output, more overlap.
Now you'll have revise the manual to say 75% overlap.This kinda hit home as I never gave over lap a 2nd thought and had no idea what I do.
SO yesterday, I did a lot of spraying and paid attention and I'm actually at around 70-75%!!! I had no idea and assumed I was around 50%.
First time I have been wrong this year. LOL
I just did a few sample spray outs on some speed shapes tonight. Only one coat of UC but real slick. Added retarder to get it to flow out. I think retarder is the special sauce. Barry has said some people add up to 50% retarder in the final coat.
I haven't seen anything about what your conditions are and what activator your using.
Since Universal isn't reduced, the activator selection is crucial. Always go a step slower than you think you need.
Yes fan runs between coats.
You run the ran constantly between coats? I thought you turn the fan off after the cloud clears, then back on when you start spraying the next coat.Yes fan runs between coats.
