[Public-list] Cleaning Cowls

[Villo Marmei]

Hello ye Albergers near and far.
I am interested to know how one can clean the 4 PVC Flexible Cowls (Air 
vents) and Winch Handle Pockets  that we have on our boats ??
Mine look terrible and they have some black dark mould spots, that I can 
not remove with anything...some liquids even melt the surface a little but 
do not remove the dirt. Javex makes the look yellow.
I also, would like to know with what Red paint I can paint the insides of 
these air scuppers. I am considering Tremco Red Rust paint.
I painted years ago, the inside wood drawers and covers with Tremco Rust 
paint (2 coats) White mixed with a dash of Yellow and it looks 
terrific,clean and new after all these years. Looking forward to your 
comments....
Happy sailing... Villo KC-618
