Registrarion Numbers

by Jim Kronholm
(Bristol, WI USA)

I just finished my wood runabout with five coats of Interlux varnish.

Now all I need to do is apply numbers to the hull to make her legal.

I'll be re varnishing over the numbers every year, so what kind or brand will best accept the new varnish?

The numbers can be printed on rice paper, on vinyl, or just painted directly onto the hull.

The better quality vinyl lettering will last 3 to 4 years in direct sunlight, on a garaged or trailered boat they could last for ever without covering in varnish.

The vinyl will last longer than any varnish you put over them.

There is a tendency for the varnish to crack and peel, and take the vinyl numbers with it when the lettering shrinks and expands due to changes in temperature.

If you use numbers printed on rice paper, spray them with 2 or 3 coats of a clear lacquer before you cut them out.

You can print the numbers or even pictures, names, logos, drawings, etc. on rice paper using a computer printer.

Print outs from an inkjet printer need a light spray of clear lacquer to seal them or you run the risk of the ink running, laser jet printers are not as prone to this.

Then just sand the wood with 200 grit, lay the paper on the wood and apply two coats of epoxy resin.

Finish with a marine grade varnish with 400 grit sanding between coats.
