Some more questions about waterborne…

Hi everyone. I have a few questions about waterborne. I’m a hobbyist going to try practicing with waterborne again and I don’t have a booth.
1. I have almost a full gallon of Lesonal ProAir clear left. From what I read, Sikkens and PPG seem to have smilar technology for their waterborne. Do you think
the ProAir can be sprayed over PPG waterborne?2. I’ll be using a hair dryer to help flash the basecoat (cold setting). Is it possible to add a bit of isopropyl alcohol to the basecoat to help it flash faster?
I know not all waterborne paints are fully waterborne, but from my research Sikkens and PPG are “true” water paints and they seem to be the top choice. So, I think
adding isopropyl alcohol should help a lot.3. Sikkens calls for a 1.4 tip, some members here recommended 1.4HC. My SATA 3000 HVLP has 1.3. I have an Iwata LPH400 with orange cap and 1.4 tip.
I used to spray Diamont and the Sata was awesome at spraying mettalics. Much easier and better than the Iwata IMO.
My question is: how would both these guns perform?
I’m guessing Sata would be better suited for PPG, Iwata for Sikkens. Anyone sprayed Sikkens Autowave with LPH400, 1.4 and orange cap?4. Would a mixture of 1:1 water and alcohol be good enough for the final wipe?
Thanks everyone.

Ok…
1. Sikkens and PPG are different brands. You can spray it over the base, it should work. I just can’t say that it won’t delaminate later on.2. Yes, iso flashes fast, but I don’t see how it would speed anything up. All adding it would do is dilute the colour and change the viscosity. The iso will flash off fast, but the rest of the water in the paint will still need to flash out. I do NOT recommend this. For drying, just make sure the area is warm (room temp) and has lots of air movement. Both PPG and Sikkens can flash off very fast.
3. Gun prefrence is totally dependant on your style/prefrence. I think my Devilbiss Tekna with a 1.3 (for PPG) or a 1.4 (for Sikkens) sprays them best. Your 3000 HVLP will work ok with the 1.3. Heck, it might work just fine, especially if you aren’t doing too large of jobs. I would experiment with the guns you have first then decide if a different gun or going to a 1.4 will work for you. The PPG sprays very nicely from the 1.3…
4. For a final wipe on metal, you still want to use a solvent based cleaner (to remove solvent based contaminants). You can buy cleaners to remove water based contaminants. Iso. alcohol works well, however, I think it is best at 70% (30% water)
good luck with gettin ppg, i could be wrong, but last i heard, they’re not sellin it to the general public. i had and any shop who converts to ppg enviro had to take a 3 part course, convert with confidence program before they let us have it.
i agree with ben, don’t add anything to it either one, your just going to mess things up. there not just a striaght type of water paint but more like a latex type paint. as for your guns it would depend on what you like.
just about any of the guns you listed will spray wb paint, it depends on what you fell comfy with useing.
i’m sure you can put any clear over any base, but however, like ben said, you could have problems down the road.yes you can use lesonal pro air clear over ppg base coat, i use it every day at my shop. i have very good success with ppg, i defenitly would not recommend adding anything to it. i would suggest using a waterborne cleaner before applying the base coat. a salon style hair dryer would be perfect to get the stuff to dry, you can use it on hot setting but hold it back a distance.
Thanks for reply everyone.
So no to isopropyl alcohol.
I can get the PPG waterborne from the local store that sells them. Not sure which one is more user (hobbly) friendly, but from what I’ve read Sikkens seems to be the top choice. PPG is a lot cheaper though.Thanks again everyone! Appreciate it.
