So how does this plug work?
put in before lamination then sand to open cup
You can install them like a regular plug too!
I like Mel Ross’ O’fishl glue-on leash discs too !
I laminate.
I install plug.
I hotcoat.
reason numma one: give the plug goo summin to grab a hold of other then just foam and/or stringer.
With the fin boxes I install boxes then laminate.
When I grind off the fin box covers I grind off the top of the plug too.
cheers,
randy
