Can anyone recommend a cheap black paint (maybe from Home Depot) solely for painting the inside of structures so light doesn't shine through?
How about cheap rejects from HD? Have them mix it up again to make it darker... black isn't really required, just dark. I know it's latex paint, but it would work for your use. Also Walmart sells paint on the very cheap $8 a gallon if you have to buy new. Quarts should be even cheaper and life time supply for most for this use. A cheap quart has to be cheap than one rattle can. Steve
Thanks Steve, I didn't even know HD had rejects. Thanks for the idea and the Walmart info. Just confirming here, but latex doesn't damage plastic and will stick to it?
It won't harm the plastic at all. It may crack over time but that's an easy fix. I would be careful if lighting the building and be sure to keep it away from the walls but you should do that anyway. You just have to ask for it when you get there. These paints someone had mixed but didn't think it matched what they were after. Quarts are like a $1-2 and gallons can be $5-10. If you really want to be cheap, and these day who doesn't, buy a gallon of dark green for your backdrop (assuming it's right for your layout) and pour off enough to almost fill an old jar like a large mayo jar for use as "interior" paint. Top off both containerss with water and shake well. You wind up with FREE interior paint and enough backdrop paint that flows well for $8.00 (assuming Walmart paint). Walmart paint works great for scenery paint, backdrop sky, mountain etc, roads or just about anywhere you need paint in volume. About the only place I wouldn't use it is on the outside or buildings and rolling stock Steve
I actually saw a "CP Spray Paint" for 94 cents a can at Walmart, in black. That's even cheaper still. Do you know if that works with plastic? Haven't found anything on it on the net.
Most rattle cans are safe for most plastics. Not familiar with CP and couldn't find a link for it on Walmart. I would read the can before buying and then do a test on a piece of scrap just to be safe. The up side to rattle cans is they do dry fast Steve
