Hi all,
A few years ago, I’d built a F&C Reading XMp 36’ boxcar and when I took it out of storage I first did touch ups with the same Tru-Color Reading boxcar paint and that went um not great, as Tru-Color paints are usually not brushable. After some touching up, I’d given it a coat of Tamiya clear flat, and thought okay, this is done for now. Well, some places on the paint started to bubble and the paint, maybe a quarter of it, easily scratched off with my finger nails and I have numerous areas that are back to bare resin, yet on some other parts of the model, the paint is sticking without issue. I’d try carefully to scratch at it, and if it came up easily, I’d keep removing paint until I found places it seemed to actually be sticking to the resin. I contribute this to poor preparation techniques on my part a few years ago when I built the model. I think I hadn’t worked hard enough to clean the mold releases, skin oils, and more when I’d built it. Recently, I’ve had good luck with Tamiya gray primer sticking to my resin models and thought I’d try carefully applying clear flat coats from Tamiya and than repainting with the Tru-Color paint. Since the model is white resin, would a white primer be good to start? I’d be concerned using using a gray primer would create different hues around the model’s painted surfaces.
Anyone else have this happen with Tru-Color or other brands of paints not sticking to resin models? If so, what did you do to fix it? I’d rather not completely strip and repaint but I’d like to not have to deal with paint coming off easily over the years.
Thank You
