Krylon Paint and Etched Plastic.
Posted by SMH on Friday, October 06, 2017 10:13 AM

The last several cans of Testors spray paint I've bought have given bad results. I don't know if it's old paint or a manufauturing problem. The paint blobs out and goes on thick.

So I decided to give Krylon Made for Plastic paint a try. I thought if it turns out good I'll have a local source of paint and I don't have to mail order or travel 75 miles to a hobby store.

Well it etched the plastic, not bad, but it did. 

My question is, is there a fix?

Only solution is to sand the plastic til it's smooth. You will want to consider using a primer to prevent that issue in the future so you can continue using Krylon. Sorry to hear that about the Testors paint, I usually have that issue with their paint when I'm respraying their gloss colors for a second or third time.

I've had a couple spray sessions ruined a couple kits using Krylon. Cracking, orange peel, poor coverage. I sprayed in two light coat sessions. Since I live in Central NY, weather was not a factor nor had humidity issues since I switched to using Rustoleum brand. Rustoleum is a better buy for for spray painting large areas of any kit.

I have given up on Krylon paint recently.  I used to use their sandable primer. It was great stuff- learned about it about twenty years ago from the old newsgroup rec.models.scale.  But it recent years they have been changing formulas quite frequently, and the newer stuff, supposedly optimized for plastic, just does not seem to work that well.  They have gone the route several other paint companies have gone, putting out a paint that is supposedly both a primer and color paint.  But the stuff is not good at either use lately.  In some cases it seems to react with styrene, in other cases it is not compatible with popular model paints.

I have recenty been using a Rustoleum primer, and occasionally use Rustoleum's Painters Touch, which must be left to dry for even longer than MM gloss (feels dry but will react to anything going on over it until about a week's drying), and it goes on really thick, good only for large scale models with little surface detail.

Other than the primer, I am sticking to model paints!

Thanks for the replies. I've been a long time Testors user and love their products. I've had troubles with the last 3 rattle cans I've bought. One was Aqua Green and the other two where Gloss Black and Flat Black that where bought in different stores. They sprayed heavy and seemed to never dry. I think I'll fire off an email to the company and see what they have to say.

I doubt it’s a quality issue. Sounds to me you’re spraying too close and too heavy on the model.

All the MM flats dry pretty fast, but the gloss ones are very slow drying, normally between two to three days (and it depends heavily on the weather).  Since I like the paint, I have built a drying box, running at 105 F.  Gloss MM takes 12 to 18 hours in there.

How do you maintain 105 F? That sounds intresting.

I built a cabinet in my garage to store stuff that I don't want to freeze in the winter. I use a 25 watt bulb and that keeps things from freezing. Not sure what I'll do when we run out of old style bulbs

Thats what I would think, but the cans didn't produce a fine spray, they just kinda blew the paint out.

I use a 60 W in mine.  I hooked a dimmer in series with the light socket so I could adjust temperature, but found I need to run it full blast to keep it at 105.  No regulator.  My basement runs at a pretty constant temp, so regulation really not needed.
