Do you add thinner to clear coat?
Adding a small percentage of reducer will thin out your clearcoat, making it easier to atomize and give it a better flow while its drying out. I do 10% on 4:1 Clears and up to 20% on 2:1 clears.
Is activator the same as hardener?
From a general standpoint activators and hardeners do the same thing; initiate cure of 2K products. However, you must use only the activator each product calls for on the tech sheet and not interchange hardeners/activators from different brands or products.
Why did my clear coat wrinkle?
A few different factors can cause the finish to wrinkle or crack when applying another coat of paint. The most common – is applying the paint too thickly – which makes the surface of the paint dry too fast and not the underside. When you re-coat, the solvents in the paint shrink and this causes the wrinkling.

Can you paint a car with airless sprayer?
Yes, it took a LOT of elbow work, but it really does look nice! I’ve painted a few cars, which means anyone can paint cars! An airless sprayer will be difficult to spray a finely atomized mist, but it may be possible if you use more reducer in the paint and spray additional coats.
Why is my clear coat not glossy?
The likely cause is that the paint was applied too thin per coat or the nozzle was too far away. A coat thick enough to get a glossy sheen is seen but not too thick that runs develop is the proper technique. Practice on a similar surface is suggested.
How long can base sit before clear?
You want to give about 15-20 minutes in between base coats and then about 20-30 minutes after your last base coat before you apply the clear coat. If you wait 48 hours, the base coat will be too dry and the clear coat will have a harder time sticking to it.
