2k Clear – Spraying Differences

I’ve never sprayed any 2k before. There’s two clearcoats that I’m looking at, one is medium solids and the other is high solids. Will they spray a lot differently? Is medium solids easier for a beginner? I’ve only sprayed 1k products before.
what kind of gun are you using?
medium solids will atomize better but i dont know how much better
high solids (and medium) really need higher pressures to atomize finely, unless your using a quality gunThanks. I was wondering if one was kind of thicker as it came out of the gun. I’m using an AirGunsa AZ3 HTE2 with 1.3mm tip which people on here have said puts out a really good finish.
EDIT: that is my main gun. For this job as it’s a set of wheels I will be using a mini gun, Kestrel/Deltalyo 828 with 1.0mm tip. This is supposed to be in a similar league to the AZ3.
Well.. when I tried clear coating with MS and 1.0 nozzle I got quite corn cob and orange peel finish.
If you must use the mini gun.. reduce your clear apply 2-3 coats.. although I did wheels few months back with a normal size gun and did not had nay problems using it..Your best bet is use the AZ3HTE2 for the clear.. check the tech sheet and go accordingly with the mfg specs on spraying it.
What brand clear do you want to use?
When painting wheels with a full size gun the width of the fan will catch you out and you can very easily recover areas already done with resultant runs. You can wind the fan in and reduce fluid and air flow but that just chokes the gun up so it’s not working the way it should.
A smaller gun will allow you to get around all the spokes putting clear just where you want it and a 1.0mm tip will work fine with most clears. The little guns tend to atomise finely so you can get a wet coat but quite thin, which is what you want. It can also be a lot lighter which is good if you have a lot of wheels to paint – holding a full size gun with full pot out at arm’s length with all the movements needed to do a wheel can be quite painful.

Also you don’t need to atomize clears into a fine hairspray mist like alot of people think. All you end up doing is blowing out all of the solvent during travel and start piling on dry clear. This creates more texture and in turn people start piling on more. Bad scenario.
Good gun control and a nice clear, regardless of solid content, make the most difference.
I have lower solids clears that I spray at higher pressures than higher solids low voc clears, it is more chemistry dependent.
