Gear & Resources

A running list of products we have actually used on Persistence, our 1981 CS 33. No manufacturer has paid us anything. Notes reflect our honest experience.


Hull & Deck

  • West System 105/206 EpoxySlow hardener variant for cold-weather work and infusion. Gives significantly more pot life below 10°C.
  • West System 407 Low-Density FillerFairing compound mixed into cured epoxy. Good sandability, used on deck repairs and blister fill.
  • West System 403 MicrofibersStructural fillets and bonding. Used on interior sole knees and chainplate backing plates.

  • 3M 4200Sensible alternative where removability matters. Deck hardware and portlight frames.
  • Sikaflex 291Teak bungs and non-structural deck seams. Good UV resistance, remains paintable after cure.
