I will NEVER use Krylon on a model again.
Decades ago, I superdetailed an ABBA set of Athearn F7 units that I converted into the ERIE’s F5, 710 ABCD. I really pulled out all the stops and they were really impressive, Protopowered, all four units and they could pull over 60 cars on the North Shore layout. They have, of course, now been superseded by Genesis and other newer units. I even got a large blue box that had foam in it, and they could be carried around in that box, just like a brass set.
I painted them with Floquil, and used Accucals and Accupaint for the yellow nose. Lots of drying time between the two, and there wasn’t any reaction between the two paints or the decals and the Floquil black. I overcoated them with Krylon, on the recommendation of a fellow club member.
So after about two years or so, one day I took them out of the box and they felt a little “sticky.” And then I noticed the fingerprints in the decals. And the wrinkles in the stripes. And then the fellow club member said “Oh, yeah, I’ve seen something like that on some of my models . . .”
Hope someone can learn from my bitter experience.
