I've posted this question on MEPD as well...
I have tried two different paints on the vinyl tubing I am using on the barrel of the gun:
Standard indoor / outdoor spray primer
Krylon Fusion Plastic Primer
Both are still tacky and will not cure.
Any suggestions on what will adhere and cure on flexible vinyl tubing?
I have tried sanding, washing, and cleaning with alcohol prior to paining.
Thanks
