Have a look at Swish. I have a medium weight with hood and love it. I do paint them in the summer when I have washed them with Fabsil and if the weather has been pouring in the winter and they come in wet, I dry it out and give it a spray with Fabsil spray.
Hi Nikicb no I haven't tried it. I always prefer to hear what others think of a product before I venture forth. Would be interested to hear from anyone who has.
