Model Railroading > Painting Delrin HandrailsDate: 06/14/21 08:36 Painting Delrin Handrails Author: NYSWSD70M Is there any new technology or method(s) to use to paint Delrin handrails?

If you aren't up to sandblasting, a wash in warm soapy water and a good rinse help with adhesion. Some does a light spray of a good primer like Tamiya's.

Date: 06/14/21 16:25 Re: Painting Delron Handrails Author: wabash2800 I use a cheap Soda blaster from Harbor Freight with baking soda with great success. I don't have a paint booth, so do it outside hooked up to my compresor. I spray into a cardboard box to catch the baking soda.
Victor Date: 06/14/21 16:59 Re: Painting Delrin Handrails Author: csx4793 I swear by a soda blast followed by duplicolor adhesion promoter you'd find at the auto parts store, I've been able to bend and somewhat twist my handrails without any sort of flaking of the paint.
Date: 06/14/21 17:08 Re: Painting Delron Handrails Author: JUTower I've had very good luck with the adhesion promoter in spray cans. It's expensive and very stinky (fumes) but extremely effective at solving this problem with the shiny/engineering plastic/flexible handrails.
Date: 06/14/21 18:27 Re: Painting Delron Handrails Author: chitownjeff I'll concer with the use of adhesion promoter, works great, but it has a very nasty smell, I sprayed it in the basement once and thought I was going to poison the whole family up stairs.
Even with a paint booth with a outside venting I will not spray inside, only outdoors even in the middle of winter. Jeff Date: 06/16/21 06:51 Re: Painting Delron Handrails Author: jburek I've had great success with automotive adhesion promoter. Don't have an issue with the smell - do use a spray booth that vents outdoors.
