Well, It ain’t quite gloss and polish but it’s pretty damn close and not very hard to do:
I was fixing some nasty rail delaminations on friends 10’ fifteen year old resin tinted Hap Jacobs that’s otherwise in pretty nice condition and wanted to freshen the bottom up. I decided to try and get to an acceptable end product as quickly as possible. Once I got the delams fixed and rough sanded to 150 (dry) with a sanding block. I broke out the wet dry and went from120 to 220 to 500 to 1200 in areas that I’d repaired and machine sanded the whole bottom with 500 & 1200. Then I put a little polishing compound on the board and spend about 3 or 4 mins with it. I wiped off the the bottom with a damp rag and put one coat of high quality auto polish on it and buffed it out. The whole process of cleaning up the bottom took a little over 20 minutes and it looks real nice to me.
It turned out so well that I decided I’d try the same process on a couple of epoxy boards that I’ve laminated and one of my favorite old poly boards. Wal-la they all look just about the same. If that shinny look works for you it’s certainly worth a go.
