Years ago I did a lot of custom painting, and at the time my method for painting handrails (delrin, acetal, etc) was to mix some automotive flex additive in with paint.
Now that I've started using water based paints (Pollyscale primarily, still have to try ModelFlex) I'm not sure what to do. I know about the paints for R/C cars that is flexible, and I use them for hand painting handrail ends yellow or white. But I need to paint the whole handrail set Conrail blue, and to try and mix an exact match would be tough.
I have read mixed things about using "plastic adhesion promoter", I know there was an article in MR about using it, but I'm not sure if it's okay to use with water based paints. It's a laquer based product, and the instructions tell you to paint the items within 10-20 minutes of applying the adhesion promoter. I can't see that working very well with Pollyscale, or am I wrong?
I've also read about bead blasting, soaking the parts in vinegar, etc.
So what do you guys do about painting handrails?
Thanks in advance for any advice!
