I've used about every QD known to man. As a fan of the Prima products in general, I really like this QD. It's as slick and easy to use as any I've come across. This one has a leg up on FK425 and OQD because you can use it on glass and it doesn't leave a smeary mess. Most QDs cannot do that well. Of course, it works best with only Prima sealants, but it works well with any LSP I've tried it with.
