I purchased a cover for my 152 from Bruce's Custom Covers almost seven years ago. I was getting ready to replace it as the stitching on the edge was failing and it was looking pretty ratty. I forget how exactly, but I became aware that they advertised a lifetime warranty against that sort of thing and if the cover is in otherwise good shape they will repair it. I called and they confirmed it. I shipped it back and today it was returned. They paid return postage, cleaned the cover like new, replaced all of the edging and corners with new material, and basically rebuilt the cover all at no cost.
All I can say is WOW!
