Looking for Spray Foam Applicator Rec's

Looking for recommendations for a foam applicator. Looking for the handle and bottle as I don't want to use my wand. I figure it'd be cumbersome. I'd rather have a smaller one like my paint gun.

Also a stupid question - Don't laugh.... Do you just spay on and spray off and done? or do you actually take a cloth to it before hosing off the foam? You were warned that it was a stupid question. I have just never gone this route, but looks like an easier route and will make my pressure washer not sit so much.

Now ready? Go!!
