oh btw as you may figure I am a canvasser upholsterer
just sondering did they use the seamark for the aft curtain also it isn't recommended by seamark as you need some breathable canvas on the boat

Mike,Thanks so much for the great info.Yes,I am familiar with the mold problem,and yes they did use the Seamark for the aft curtain as well as everything else.
I can't blame the fabricator as I'm the one who wanted the seamark,and requested he use it.
I wanted something that was completely waterproof,yet soft.I had used "Top Gun" fabric on previous boats,and it was tough,but very stiff.I figured the Sunbrella Seamark would be softer yet still completely waterproof.It is all of that,but it looks like I should have done a bit more research.
I still love it though,and as I mentioned,it's still in excellant condition other than the thread and clear plastic.
As for the mold,I found that a product by MDR called amazon mildew stain remover does a spectacular job in removing the mold and mildew,and it's a non chlorine product.
After the mildew is removed I apply a coat of 3M mildew block. It's a spray on or sponge on clear liquid that works extremely well in preventing mildew from reoccuring.It will easily last more than a year.
These two products have been a godsend in controlling and stopping the formation of mildew.I got them from Defender Marine suppy,not cheap($25.00 for both)but worth the price.
I found the biggest mildew problem to be when the boat is closed up for long periods in the hot summer months when it's humid. I don't have that problem when it's shrink wrapped in the fall into spring.
I'm going to have the canvas guy up in Niagara NY(where the boat is), re stitch it with the solarfix thread .that's all he uses,and Ill look into a thicker better grade of isinglass or maybe the Strata glass.
While its there I'll see if he can sew some kind of vents or other form of ventlation in the aft curtain,so that it will breathe better.For now I leave the side curtains open a bit.
Is the Srata glass outrageous in cost?,and do you think it's worth it as compared to a 40 gauge double polished vinyl? Is the weatherability any better?
Thanks agian Mike for the help.
