Advice for painting fubber T tracks for ROTJ blaster

I was looking to finish my ROTJ boba blaster. I was curious how painting the T tracks go. Mine are rubber and I have a concern about the paint drying.

Has anyone had any problems, know of some tips, or threads to help.

Thanks

Just use a primer, a plastics primer. That should solve all the problems with paint.

Krylon makes a black primer too.

Thanks guys, I just did not want to make a great gun and then have the paint never dry.

thanks again
