Re: spraying Interlux perfection paint
Basically, it's a 2 part polyurethane. The hazardous ingredient is cyanide. It's a very low percentage but still potentially harmful if inhaled as mist from a spray gun.
On the plus side, it's as glossy as glass, UV resistant, ignores gasoline and most chemicals, is VERY scratch resistant, and remains flexible on fiberglass. Application is newbie friendly, as it flows together smooth and is run resistant.
I did a classic '75 GMC motorhome in 2 shades of blue, gray & white with it using a Binks cup gun, turned out beautiful. 5 years later, it still looked exactly the same.
If there's a choice, choose the thinner with longer cure times, so that it blends together where you start & stop.
