leash plug installation

hey yall
ive got this old longboard that doesnt have a leash plug, and its really pissin off the cops on my beach. supposively im gonna get a fine of 500 bucks next time. i was gonna just use polyester resin with a square of fiberglass cloth shredded up in it, but some guys at west marine(boat store) hooked me up with some stuff called Marine-Tex.http://www.westmarine.com/webapp/wcs/stores/servlet/product/10001/-1/10001/72273/10001/96/11160/4
do you think this will work alright, or should i just suck it up and buy a half gallon of resin?
thanks
