Drifter, I went to this site and picked out the numbers that I thought pertained to my boat and then called the number on their website. A young gal answered that was really helpful. I told her I needed some test swatches to make sure which pattern and I mentioned 304 and 308. She ask for the year and make of my boat and she said she wanted to send me one more because Grady had used it some that year. The swatches were free and it turned out the small areas I needed to repair could be covered by the sample pieces so I never needed to buy anything. They work great. Good luck
