    Planning to tackle some of gel coat cracks on my 2006 62 Flybridge. Does anyone have the color spec for the Neptunus white gel coat?

    I don't think you'll be happy with the stock color as your boat has been exposed to the elements for 14 years. Better to go to HD or Lowes and pick up a bunch of "white" chips to find a color match to the surrounding area and them find a gel coat to match that.

    Thanks; That may be a option. I know they have computerized color analysis, but I’m not sure they sell gel coat.

    Usually the gelcoat guys start with a basic white and tint it to match the boat's gelcoat.

    That is what our contractor did. Looks like nothing was ever cracked.
    I think the Lowes, Home Depot color cards are to work on tinting the white gelcoat.
    He sprayed the gel.

    I wouldn't expect HD to have the gelcoat, but they have color chips in every shade of white. Match those against your boat's color, then shop gelcoat.

    Whenever I ve had some repairs done, I had the guy remove a small storage door and take it to his gelcoat supplier in FTL to match. Perfect match everytime.

    Most good gelcoat applications, unless a small area, are sprayed. Make sure the painter has gelcoat experience - much different than spraying Awlgrip. Did any of the underlying cracking or crazing need repairs? 14 year old gelcoat is probably going to be a custom mix unless you spray to edges where the color/shading transition is not apparent (Pascal+1) That's why for a small hull repair the painters often spray the whole side of damaged hull, stem to stern.
