    Bud, I know you were gone from Westsail by the time the 28s were being built, but maybe you have some insight into this anyway.  We're hauled out right now and I noticed some blisters from my waterline down about 12".  When I dug down, they were just blisters in the white paint that was on top of what appears to be a colored gel coat.  They did not extend into the gel coat. The color matches the bulwark color (before we painted it).  But, if it's the boot stripe, it would have been some 12" wide and most of it would have been under water.  This is reinforced by the fact that I took the top gudgeon off and, sure enough, the colored stripe is evident there as well.  Why would they make such a large boot stripe?  And any ideas why the, apparently, original white paint would have blistered on top of the colored gel coat?

    Thanks,
    Steve

    When a fiberglass part is laminated in a mold, the exterior colored gelcoat is applied first.  If it is white gelcoat, then a dark colored gelcoat is them sprayed on over the white.  When the lamination is done, this permits the laminators to see any dry spots or trapped bubbles in the fiberglass they are laying down and squeege them out.

    This backup gelcoat is usually black, but if a colored sheer or bootstripe color is sprayed on, then it may be the backup.  Tape is put on the mold in the area of the sheer and bootop stripe, the white is sprayed on for the hull color, the tape is pulled off, and then the the colored gelcoat sprayed on.

    Mystery solved ?
