Well my local paint store kinda convinced me to paint the 914 with Dupont centari, Single stage Enamel, I'm using the low temp reducer, and not the "gloss enhancer"... So the directions say 8 parts paint 2 parts reducer...It kinda warm her and the garage is staying at mid 60 constantly.... it is mega thich and I'm having to go more like 8 paint and 4 reducer.. but it is mega dry and doesnt flow out.... and mega orange peel... I 'm using a Sata JET NR 95 HVLP gun and a 1.5 tip, which is what I have always used, but I havent ever shot out singe stage in it,,, What the hell is going on. I used to paint a fair amount, But in the last 5 years the only thing I have shot is panel repair on our explorer after 2 separate accidents, last time was about 2 years ago...

OK did some tests,,, I tried the lacquer thinner on the engine hatch since it had came out the worst, some how I missed some debris and when I sprayed the targa bar from underneath it blew a couple of chunks on the lid... The new paint did come off but not without a fight, it was a gooey sticky mess,,, as a alternative I wet sanded and did a quick buff on the top of the targa bar.. and the paper didnt really clog up too much just a bit, and it did seem to buff out decent but all I had on hand was some foam pad polishing glaze , and it came out real decent considering it wasn't a cutting compound... and it didnt seem to gum up.. the paint doesnt seem sticky,, if I press firmly with a fingernail it doesn't leave a mark, but if I press as hard as I can I can leave a mark.... when I was getting the paint the salesperson said that some guys will use hardener in the last coat, but suggested I didnt because it was alot easier to run and since I had not shot some paint in a while that is why they steered me away from the hardener, but is was suggested by someone earlier that if I hse hardener on a later or last coat it will cause problems... Again they said most of the guys that are using the centari don't use hardener... do they not have a clue? or is it ok? So What to do?????????? I shot this last night,,, today is Christmas eve, tomorrow is Christmas day, So no stores will be open,, Can I wat till Saturday to "lacquer strip the paint"I'm sure I dont have enough lacquer to strip the whole car ,NOT to mention it will be a mega heartbreak doing all that, Is it absolutely necessary? or can I wet sand the orange peel out and try again MAYBE using a hardener,,, or wet sand and go urethane /base coat clear coat, I think urethane can go over about anything, but can someone confirm this and would I have any problems having this "unhardened added" paint under it?... Man I feel like a idiot its been too long since I shot some paint ,here are some shots of my problems.

targa bar quick sanded and quick foam pad buff this shows a bit of reflection it hard to photo
