Hi.. Just wondering from the top of my mind..
Would clear coating with 1.0mm nozzle be more effective to minimize orange peel?probably not, in fact it would prbably create more. Keep the 1.4 tip. Try using a slower activator and laying the coat wetter. The way you see it when it is wet is the way it will look when dry so if it looks peely right after spraying add some more in the spot and you should be good.
Some of the new low voc high solid clearcoats spray better with a smaller tip but I wouldent go any lower than a 1.2
Every clear reacts a little different and each gun is a little different. Anything from a 1.2 to a 1.4 would be ideal. Keep in mind with a small tip, you may have difficulty achieving minimum film build (particularly with clears with lower solid content).
I will go today to a scrap yard.. get myself a panel.. treat, fix, prime the panel.. apply solid black base coat, then do a test, half with 1.4mm standard pressure, 1.4mm max pressure, 1.0mm standard pressure, and max pressure..
I will be using 2K MS build CC.

reduced with

I will try to post the pics here 🙂As you have suggested.. it did not make orange peel.. it made Lemon Skin 🙂 Like worst finish I have ever tested.. My noname HVLP had sprayed pretty much good.. it might need a little buffing.. but all in all I kinda like the finish.. The gun is h-827 china sh*tte.. but it sprays kinda good.. I kinda dig this gun..
with HVLP guns you normaly require larger tip sizes than with compliant guns for clearcoating ,a 1.0 compliant gun wiill lay a superb finish but you would have add extra thinners to get it through the tip at a reasonable rate to keep things wet enough as it will be extremly slow going compared to larger tips ,my preferance for a supr fine finish through a compliant gun is a 1,2 set up but used correctly a 1.4 can give ultrafine results as well ,mostly people forget they can restrict a 1.4 to spray exactly the same as a much smaller tip so rather than changing you tip try adjusting your fluid control nob uuntill you get what you want
Well.. the 1.4 that I have got cleaned in thinner and ultra sound.. You won’t imagine what crap came out of it..
As far as the mini hvlp 1.0.. it has a leak on the nozzle tip where the needle contacts the nozzle to make it shut.. Tried to fix it.. can’t..Last night I had sprayed a test panel for my car to color match, cleared it with 1.4, 29psi, 3/4 fan, 1/2 material..
Got the factory finish with a el cheapo gun… So that is what I need..Regarding a CC gun I’d like to get either

the second one is kinda a copy of sata in performance of finish.. at least that is what their representative is saying..
