Synthetic Paint Advice

[Hudzoyne]

I have recently painted a car with synthetic and hate the finish it has given and how it went on. I much prefer using 2k..... Now I have bought all the 2k stuff and an isolater to spray over the synthetic.

My question is how long should I leave it before I can spray the barrier coat over the synthetic? The general consensus is the synthetic takes an age to dry! I have it in a sealed workshop where I have had the space heater on for the last coupe of nights drying it. It will wet sand without rolling and can be sanded with 800grit dry on the DA without rolling.

Couple of weeks at least for it to go decently hard unless you can leave it in a spray bake oven for an age. You can generally get a decent finish with synthetic - what went wrong exactly? You can also spray it hot with a 'hot pot' that you use instead of the normal pot for your spray gun - it plugs into a kettle plug for a while before you start painting and basically does what it says - you can get a really good finish like that but it does take even longer to dry as you use much less (if any) thinners.

I just can't seem to get a decent finish with it and it can't be flatted off and polished like a decent 2k. I only bought it because it was cheap but I wouldn't use it again, a lot of online reviews and opinions say its best avoided too. Should have read them beforehand.

If it's able to be sanded without rolling now surely it doesn't need weeks??? I can't wait that long

If it's not completely dry then it will continue to vent solvents as it cures/ dries, I would have thought this would cause reactions with the new paint? Can you do a test panel to try it out?

Reactions should be dealt with by the bar-coat. I am more worried about the paint shifting underneath and continuing to level which might crack the harder 2k being laid on top
