I'm by no means an expert and learned how to spray these over the last week so keep that in mind.The Bad:I sprayed the two quarts of Championship White, ½ quart of Performance Red along with 2 quarts of gloss clear right from the can to the gun without any product issues. Anything that went wrong was due to me and not the product. I was hoping to wrap up this project and opened the 3rd quart of Gloss Clear and noticed it was cloudy/foggy. Hoping it wasn’t going to cause any issue I tested it on a small area and sure enough I noticed the Performance Red turning what looked to be more pinkish. I’m guessing whatever was wrong with this quart reacted with Performance Red and it discolored it and/or made it cloudy. I waited for it to dry and re-shot that area with another coat of Performance Red and then got my refund on Amazon for the quart. I’ll use that money to go to my local AutoZone to pick one up today so I can finish this project rather than wait and see if I receive another defective fogged quart from Amazon. I couldn’t find a vendor to contact to let them know that their warehouse stock may be defective.My comparison to Rust Oleum rattle cansI have been using rattle cans for years with pretty good results (I wouldn’t paint a car with them but my smaller household items look very nice) but wanted to give this type of paint (Entry level pre-thinned “Automotive”) a try and wanted to see if there was a significant difference between it and rattle cans.Short story - I'm going back to rattle cans.It's an okay finish but following three coats of Gloss Clear (I did not sand/buff and polish) it’s not better than what I can do with the Rust Oleum products and I don't usually top coat them with their gloss clear nor do I sand/buff/polish them. I have used gloss clear and then they look even better. Maybe with more practice I could improve the output for the lacquer but what really bugs me is that ton of clean-up is needed to clean the gun, it's messy pouring from a quart can and then the dirty lacquer thinner that you use to clean up needs to be disposed of properly. With a rattle can you just throw it away. Obviously, there are shortcomings with a rattle can but the convenience and clean-up is why I'm going back to them, as well as cost. I wish Rust Oleum had the same color choices in a lacquer paint as they do for enamel (Which takes soooo much longer to dry than lacquer - definitely a positive for lacquer paints but the lack of color choices is another negative). The other thing is the cost of the lacquer paint and other items needed (Lacquer thinner, paint strainers, lots of paper towels, etc). The project I did as a test I have done before using rattle cans. Two rattle cans of red and four cans of white for under $40. This Dupli-Color lacquer was over $100 more just in paint, not including the additional supplies! I really wanted to like this spray process over the rattle cans but I’m heading back to Rust Oleum.
