I have a small suraface crack on the cockpit floor of my gorgous 1979 Oday 22. I am thinking about just sanding it down as far as the crack and refilling with maybe bondo or some epoxy, then sanding and throwing some paint on it. This repair is strickly to prevent the crack from opening and or spreading and if the color looks off then thats ok. Any suggestions for best fiberglass/bondo/epoxy kits or cheap paint? Thanks.
