What actually is an automotive paint supplier. Even if it doesn't work, if you are careful not to overheat the plastic substrate in the process you won't be any worse off than you are now. Use a hair dryer, a heat gun (carefully!), heat lamps, and/or an infrared heater to heat the surface and try to force the paint to resume curing. You may be able to rescue paint stuck (pun not intended) in the glassy state by subsequently oven curing it, but usually even this will not work.Īt this point you have nothing to lose, though. If the temperature is too low, the paint will slowly cure to the glassy state over many, many hours but never cure beyond that. In the first stage, the polymers in the paint cure to a soft condition that's often called the "green" or "glassy" state (usually in less than an hour at normal temperatures), and then progress to the final, hard cure state over a period of several hours to several days. Most polymer systems, including many paints, cure in at least two stages, and the cure rate is strongly dependent upon temperature. Allowing the temperature to drop after 24 hours probably interrupted the curing process forever. How long had the shop been at 65 degrees before you applied the paint? The usual requirement is to bring the shop up to temperature at least 24 hours before you apply the paint, otherwise the air will be at 65 but the surfaces you are painting will still be considerably colder. 65 degrees would be a bare minimum for most paint systems. That said, temperature is far more likely the problem. chemistry), it sounds possible that the mix didn't include enough hardener. I painted it in a heated garage that was 65 degrees, and kept it 65 degrees for 24 hours after, then it stayed at at least 40 degrees.ĭepending on the paint type (i.e. It is now 2 months later and the paint is not “hard”. I really do not like Sherwin-Williams / Martin-Seynour / NAPA paint. I would suggest, however, to get your next spray paint from a regular automotive paint supplier.not NAPA. But, bring it inside and let it sit in a warm spot for a few days and see what happens.įrom what I can tell you didn't do anything wrong. You may want to consider finding another decklid to save all the labor on this one. At this point you may have to scrape it off and repaint. Enamel takes longer to cure and that may be the issue.not long enough in the warm environment for complete cure. I expect that this can was a single stage enamel mix and not lacquer. Lacquer should dry quickly and with no issues at 65 degrees. When a can is mixed at a store like that it should be ready to go. Lacquer based paints are recommended for the novice. This is basically the result of lacquer based paints in the hands of a novice. So you don't think it will cure if brought in the house? I painted it in a heated garage that was 65 degrees, and kept it 65 degrees for 24 hours after, then it stayed at at least 40 degrees. I did shake teh cans like crazy for a few minutes, and during. This was in a can stuff, but they mixed it on site. Specializing in Corvette & Higher End Autos for 45 yearsįerrari, Mercedes and Porsche Body Repair Approved Acrylic enamel is a single stage and will air dry in a day or so if its kept over 60 degrees at least overnite. Its also possible they mixed a single stage can for you with a paint that requires a hardener by mistake. If it is still gummy, I suggest using a scraper with a single edge razor blade and 'shaving' off as much as you can, then try using some lacquer thinner on a rag to soften and wipe off whats left. Doing that takes some skill that a backyard painter is not going to have. If I got a car that wont match, I can mix other colors into the mix to tint it (ie/ like add some silver or white to lighten the shade, or black or blue to darken it. Its also impossible to tweek it in a spray can. If its faded from age, your not likely to ever match it completely.
NAPA PAINT MATCH CODE
If its the original color, just go by the code on the vehicle. It only suggests the closest possible matches from its own internal data base. The 'reader' all the paint stores use does not give them a magical formula to match contrary to what many think. Napa is Sherwin-Williams paint, just repackaged for Napa. Did you shake the can up enough to mix it before spraying ?. Im guessing by where you are, its too cold.
