 That's really up to you. If you feel that it's getting a little bit out of control, then I'd recommend at least having an inspection so we could go, hey, look at this, look at that. We could actually bring the kit out to you and provide that inspection for you, the do-it-yourself kit, and go do it here, do it there, or just have us do it either way. With us, it's guaranteed. It's applied correctly. If you do it, it's still guaranteed because you're using materials that we would use, but you have to actually get it into all the holes.
