I have found that using 2-pot polyurethane paint or clear varnish directly onto wood works fine and it lasts many times as long as ordinary one-pot stuff.
I've always been a great fan of 2-pot polyurethane varnish, but have now come across something even better: Uroxys marine clear finish. This actually is a two-part system, but the first part consists of a primer and the second of the clear gloss finish (www.uroxys.co.nz). The product is a polyurethane, but is much easier to use than the usual two-pot type. You prepare the wood and then prime it. Either put the clear finish on the next day, or leave it until you have time and put it on after lightly sanding. As soon as it is touch dry, you can put on another coat - and another. The receommended number is between 6 and 8 coats and the varnish is said to last for 7 years. I know of one boat, entirely bright finished, that is now into her third year in Fiji and still, apparently, looks as good as new. I've found the product easier to apply than conventional varnish, much less likely to form curtains and, because it's so quick drying, less likely to get contaminated by dust, hairs, etc. It is 'gin clear', so that you can paint right up to the coloured paint line without having to mask - a great advantage, because it means that the border is sealed. Uroxys is very flexible, so it should be able to take the odd knock, although it's perhaps more susceptible to chafe than conventional polyurethane.
