Re: Stains and dyes
Posted by Stephen P on Feb 4, 2006
Rit dye disolves in rubbing alcohol which supposedly lifts the grain less than water. It will fade with UV exposure and should be varnished with several coats of quality spar.
I used a water based dye that came already mixed once and suffered a severe delamination problem (despite a seemingly successful test piece). I applied too much of the dye and it sufficiently filled the grain that the epoxy was unable to soak through and create the mechanical bond. After a year of careful babying, I ended up easily peeling the FG off the entire hull, sanded and re-glassed. This resulted in a very attractive antiqued look.
A cautionary tale.
