| Paint Systems
Working in the joinery and cabinetmaking business, we have a lot to do with paints, lacquers etc.
In my opinion, the ranking of finishes, in order of most durable to least durable are:
1. Two Pack - polyurethane/epoxy paints; very durable and able to withstand moisture, heat etc. We would use these in bathroom or kitchen joinery where others would be a risk for long term viability.
2. Acid Cat; a 2 part finishing system that uses acid to catalyse the paint. Good durability for most areas; water resistance OK, but prolonged use in wet areas will accelarate the deterioration of the finish.
3. PC lacquers - the nitrocellulous type finish as refered to above by Wheels. Good because in the right conditions you can apply several coats in one day. Don't use it near water, it will stain easily.
All the above are best applied by spraying in a controlled environment such as a spray booth. All are toxic while applying, and will "gas off" for a period of time after, and plenty of ventilation is need to ensure safety.
As with most finishes, the repair of isolated scratching or damage will require the complete re-coating of the affected panel.
Like most things, the choice of surface finishing system will vary from boat to boat, person to person depending on things like personal taste, cost, easy of application and ongoing maintenance required among others.
Having said all the above, my fitout below decks is finished with a combination of traditional clear varnish, and enamel paints.
