You have to follow the understandable guideline and you should have an effective fixing. Keep in mind all damaged windows are not the same. I had a stone hit my wife's car once she had the car windows replaced. (bad luck)! My damage was small and even though I feel the fixing was not ideal, it did help minimize the damage and hopefully keep the windshield from cracking even more. I would purchase this again.
I reside in Montana where the roadways can be sanded nearly half the year throughout a bad winter season. Consequently, I've got all types of impact marks on my windscreen. I got this kit for under $15 and filled up every single one of them. I was delighted that one fracture that happened to be right exactly in my visual field while driving is now totally unnoticeable.
This tool functioned great, repaired my car windows Halfmoon crack on my new vehicle and I can no longer find it, instructions were simple to follow even though may need to examine to spell in a few places, if I have an additional issue think I will have loads of it for several fixings, otherwise would certainly reorder, very satisfied
