I have used this on a couple of vehicles. Maskup the paint and window moulding and fill the groove. Afterwords un tape everything and you have no mess or smear lines so its not noticeableMark, try Permatex 81730 flowable windshield and glass sealant. It is very thin and runny but it worked well on my Dodge truck I tried it as a last resort before having the windshield taken out and re-sealed. It is still holding with no leaks.
