Sharp Rails

    After doing the Lam coat, do you do the hard sharp rails in the first hot coat or do you do it in the gloss coat?

the resin dam ?   It is done in lam resin as a cheater coat before hotcoat. Look at the archives.

i do mine during the bottom hotcoat(resin damming).

i think the jc 101 glassing vid shows it..............?
