Vinyl plus acrylic plus enamel paint = disaster?!?

Hi all, 

First off thanks for taking the time to answer my modeling questions, this site is the best for that!  I have an old (almost 20 years now) 1/6 scale Horizon Boba Fett  vinyl figure that I am finally getting to - wonderful detail, with just a few fixes to make.  I know from past mistakes NOT to paint vinyl with enamel paint, I have had some sticky never dried messes as a result.  learning from this, I bought some AK Interactive acrylic primer and sprayed the model with it (worked great, other than the typical super fast drying and clogging my airbrush) So my question is can I put enamel paint over the now sealed vinyl?  I am not a fan of acrylic paint and would rather go to my tried and true Humbrol and artist tube enamel.  any issues I need to be concerned with?  I did some test runs on scraps and it seemed ok but don't know what the effect would be over time.  Thanks again for the help!
