I think the durablilty of BFWD has been over-hyped. Its a 2-3 month sealant at best. Yes I know how easy it is to apply and remove. Just because you can throw a quick coat on whenever doesn't make it more durable. I have been havng water spotting issues with it. This is from rain water and not my tap water. Reminds of the water spots I would get when I use Zaino. (Car is black by the way so everything bad is amplified)
