While looking around my local Pepboys this morning I spotted this product.

Surf City Garage

Judging from other discussions here the favorites seem to be the Raggtop and 303 products. I was just wondering if anyone has used the Surf City product and if so what your impressions were of the product. The biggest difference between this and the other two are that this is a one step process. The one thing that concerns me about the Surf City product is that it states that it can be used on canvas or vinyl, two totally different materials.
