    JS550 and 650sx paint / gelcoat help??

    I'm currently doing a bunch of hull mods to my 650sx and will be doing a js550 afterwards.

    I would like to re-gelcoat both the hulls bit have been reading that it doesn't stick well to the smc hull sections.

    Is there a primer that will bond the gelcoat down, or am I going to be stuck painting the hull?
    If you're not crashing, then you're not trying!!!

    Ski situation in limbo!

    Special thanks to Chris Newmiller, and Mitchell at M&M Marine!

    OEM was painted with imron. No gelcoat as it will only bond to stuff molded with polyester resin.

    I can attest to that but not sure it was imron or maybe not on mine, just had my 91 repainted with awlgrip. Wanted to go gelcoat route but guy had awlgrip on hand and was a bit cheaper..

    I’m thinking of painting my project ski too. An 87 300sx. I just redid the aluminum on my pontoon boat with easypoxy epoxy paint. I’m thinking it will work nicely on the ski as well. I just planned on scouring the surface with sand paper and rolling/brushing it on. Anyone have experience using an epoxy paint on top of the stock paint?

    If using a gun, I redid my 85 using single stage PPG. Durability has been great and after 2 summers in the sun still shines. Ensure to wax 30 days after spraying and prior to it seeing water (to prevent spots)
