Ed is correct! Phil is correct!
Ed is correct, the masking is the worst part of the process. No matter the product, if you do a crappy job with the masking/detail there is no product that will look good when you are done.
Phil is correct, the Kiwi grip looks very good. My personal choice would be to use the white, but that is up to your taste. We have a Hunter 30 that has a Kiwi non-skid job. It went on quick and easy. The special roller is what really does the job.
