I love Poor Boy's products. Learned how to detail and use their products at one of their summer detail events that they held at their warehouse in NY before they moved to Florida. I learned on one of my previous cars, a black Honda Accord. They said my car was the most improved that day.
They have a polymer sealant now that will last you a solid 6 months. They are coming out with a new coating as well, I'm hoping it's ceramic. I usually detail my own cars as well, but didn't have the time to get to mine this year so had it ceramic coated, with a "3 year" coating. Will see how long it actually lasts.
