sealing paint....with epoxy...or Futures(now Pledge?)

Greetings everyone,

 

From my research it seems I have 3 options to seal my black pin lines to prevent crystallization futures, Patricia Nimocks, or resin.  My spray gun is acting up at the moment so I don’t think Futures will be an option.  By the way, did Futures now become Pledge with Future Shine Technology?  Patricia Nimocks’ acrylic sealer has acetone in it so I am not sure if that would be good to use with epoxy.  So that leaves resin…but is epoxy thin enough to seal with?

Do I even need to seal the pinlines?  They are about 3/16".

Thanks,

Eric
