For starters you are spraying at too high of an air pressure,max on the 4000rp is 2.2 bar or 31.9psi.Secondly a 1.2 is really going to break up the clear to very fine droplets,so I would suggest you drop down to 28psi or less and see how that goes.Also the 4000rp only needs about 3-4 inches away from the surface,so if you are spraying at a greater distance you are wasting product,with that high of pressure you are wasting material by lots of excessive overspray.On a large car (like a 68-72 chevelle)I will use 1.6L sprayable clear per coat,so for 5 coats you might not be that far off.Why you are doing 5 coats is questionable :wak
75% overlap is perfect,that should work out great for you 😉
Maybe try bumping up your pressure 3-5 psi,fan wide open and get in closer to the panel,like 4 inches and move a little faster.Being 6 inches away from the panel can cause you to go slower and get more film build causing a run or two.Let us know how it goes. 😉
A good old first gen RP with a 1.4 is most consistent with HS+ and ACIII,run it wide open at around 30-32psi.I agree with ryan about the 4000,nice gun and finish,just slower to use.I Think the first gen RP sprays the nicest out of the 3 versions but I use the 4000 the least.The trick with HS+ is to spray it with slight texture and let it do the rest.If you bag on 2 wet coats it will be on the floor,a little extra top also helps with stability.I can’t get it up here anymore but I miss it when doing completes on a hot summer day due to staying open longer and you can make a real slow mix,unlike superior 250.

Why don’t you convert those guns to a plus compliant(like an rp) gun.The GTI is slow,an air hog and not that great of a clear gun,tossed mine 12 years ago,would never use one again.The best gun going for devilbiss is a tekna.
Try a single stage urethane.Maybe your paint isn’t cured?
If you are going to reclear or rebase and reclear 600 is fine.
Your welcome 😉
Yes it should look perfect,can’t help you if you have the wrong reducer,if it feels like 220 your pressure is too high,and reducer is to fast.
Who told you that??Some solvent bases have excellent metallic control and a drop coat is not needed,others must be drop coated.Read your TDS.You really aren’t using a solvent base coat,you are using a low voc crappy base coat,not even in the same league.
Fix your rough spots,add more reducer,put on a nice medium wet coat,let flash.Make your last coat a drop coat,reduce your psi,increase your gun distance.
Transtar no mix is junk,it needs more reducer to spray right which defeats the low voc purpose,not even close to traditional solvent base coat.If you have dry spray it could be a few things,spraying technique,wrong reducer(silver needs slow or extra slow depending on heat) too small of a fluid tip,too much air pressure.What is happening is it is drying before it hits the surface=mottling.Get some slow reducer and mix it 2:1,scuff your base with 600-800 to knock down the rough spots and re-spray.
Nice,now he gets the tail light warranty 😛
Looks good Ding 😉
