In the past, I would try to touch up the varnish. That worked for a little while but new polyurethane does not adhere well to old polyurethane. The touch up varnish when exposed to sunlight for about a year starts to peel off.
|Here's the original latex painted boat, exposed to full sun for over two years already with no visible damage to the paint.|
|Here's the King Island kayak about to get a coat of tan paint. Note the previously yellowish varnish starting to turn a chalky white, a clear sign that is near the end of its life.|
|And here is one of my baidarkas with a new coat of Desert Storm Tan or maybe it should be called, Afghanis-Tan or would you prefer Afghanistan-Tan|
