[Public-List] Primer?

[Glennb]

hey Brennen, 

I just finished painting the interior of Dolce, so spent a good deal of time researching paints, primers, etc.  I elected not to use enamel, rather settled on one part polyurethane- as it is more durable and hopefully more resistant to dirt and mold growing on the surfaces over time.  I used both interlux bright side gloss white for overhead, and Epifanes 'Buff' for foclse sides.  I used Epifanes mostly because I liked the particular tone of the Buff.  In both cases, the manufactures specified sealer coat and undercoat for plywood surfaces, but direct application of two coats over existing fiberglass. it worked out very well, although I did a paint a primer coat of  Interlux 'Pre- Kote' over most all exposed FG and the few spots of plywood flat surfaces that I sanded down to bare wood.  the Pre Kote wasn't really necessary, but it does provide a smoother subsurface, e.g. Fills in little scratches and imperfections in the wood and glass.  the second finish coat really gives a nice deep shine to the paint.

worth noting that the major work for me was stripping and sanding all the old enamel layers of paint off.  I used paint stripper through several layers, then sanded the remaining, initial/original finish down to bare FG.  main reason was to get rid of 30 yrs accumulation of mold, dirt, stain, etc than had penetrated down through all the layers of paint that previous owners had applied over the years.    i didnt want any of this to penetrate through the new paint work.  this prep work was the biggest part of the job-maybe 3months on and off, actual paint work went fairly quickly- few days at most, with small marine heater on board to cure out each coat overnight.

also reinforced the fiberglass tabbing around the bulkheads and turn of the cabin mold in the focsle,  and refinished the teak bulkheads. 

glad I did it.  the interior looks new and is most enjoyable sitting there gazing into the shiny new surfaces and glowing teak bulkheads!


cheers,
Glenn B
