{{free lapping}}

what is a good method for free lapping on the bottom lamination??? i had a problem with the discolored rail line also,when sanding or grinding the lap line, should the lap be flush with the foam?

here’s another one… when filling the lam. lap on the bottom…is it better to fill with sanding resin or lam. resin…does anyone use spackle?? and another… when putting on a laminate, should it be non-catalyzed lam. resin?

oh yeah…forgot for the laminate…i meant for placing on the bottom, directly on the foam
