Krylon 5-Ball Spray Paint $2.50 at FredMeyer

I just learned that the Krylon 5-Ball Spray Paint is on sell at $2.50 (against $3.99 regular price) at FredMeyer this week.

These come in large 12 oz (340g) spray can with a logo that looks like five color balls. There is a line of warning words on the can: “Danger! Extremely Flammable.”

I am not an experienced modeler so I have no idea if those will be good on plastic model kits. But I am sure some experts here will be able to help me.

Can someone tell me what are they made of? Are these enamel, lacquer, or acrylic? Since I am not a fancy modeler, I am going to use them as one layer paint finish. No primer nor over-coat will be applied, just one layer paint in the model’s intended final color.

Are they good paint for plastic model kits? What should I know before apply? Thank you in advance.

Depends on the kind of plastic, but generally Krylon will craze the plastic something awful unless a primer is used.

Jeremy: What do you mean the paint will “craze” the plastic? I always thought it would be great if the paint is able to bond with the plastic surface.

I also saw plenty Krylon small cans on the shelf which labeled for hobby crafts. Are they different kind of paint that better suited for plastic models? They are $2.69 each, by the way.

"Crazing" is where the paint gives the plastic a fine, alligator-skin-like appearance and texture. The solvent in the paint reacts badly to the styrene and lifts bits of it up. Unfortunately, I don't have a picture available so I can't illustrate, but it is a Bad Thing.

Mr. Kenny has answered my questions in a very professional way on Friday morning. I re-post his message here to benefit other modelers.

Re: Need help on Krylon 5-Ball Spray Paint
These work great. I use them all the time, and have been modeling seriously for 17 years with four bronzes and four Certificates of Merit under my belt from Wonderfest USA.

They are a lacquer using acetone, xylene, toluene and other distillates as their chief solvents; these solvents combined are what you commonly know as lacquer thinner.

These Krylon primers are not a "filler" primer, meaning they are lighweight and should not be used as an attempt to fill imperfections like true filler primers such as Duplicolor Filler Primer or DuPont 131S, sold to hobbyists as Mr. Surfacer. Use the Krylons to detect imperfections and prepare the surface for lighter weight color coats to follow.

The Krylon is a lacquer and will "etch" styrene (it's supposed to). IF you have really soft styrene, like some of the Tamiya or old Bandai, let the stuff cure for at least 24 hours before sanding it, otherwise you will "gouge" the substrate when fixing imperfections. Also, a good thing to do is to shake the stuff for five minutes prior to using it.

One thing I do for really tough to reach or delicate applications is to decant the primer. I spray it through a drinking straw into an airbrush jar. The airbrush will give you more control. Airbrush at no more than 12-to-15 psi or the stuff will get grainy on you.

Finally, don't spray from more than six- or eight-inches away and never stop moving your hand, making sure to never let it stop over the piece. This will keep your coats light (a must!) and keep you from getting pools on the piece. Read the label directions. They're there for a reason.

I hope this helps. PM me if you have any more questions. I will be glad to help.
