Where is your quality control?
First of all I will say that the "concept" of this repair kit is sound. The solution is based on a few basic components: an anchor point, a receptacle for the resin, and air pressure to force the resin into the fissures in the glass. We all know the parts are made offshore and perhaps packaged here. Whatever the arrangement, there must be some QA process somewhere that ensures the parts have been manufactured to spec. Because they're not. The bracket that is held down with suction cups, in fact, does suck! As the resin receptacle is screwed tighter against the windshield one of the screws holding the suction cup fails and pops out. Now I am screwed because my limited supply of resin is running down my windshield towards my paint job. This becomes a panic moment for me, which was never anticipated after thoroughly reading your very clear and concise instructions. The real clincher, however, is that the resin container of yours, which must firmly press against the windshield to allow that crushing wave of air pressure to thrust resin into as many nooks and crannies as possible. In reality, resin seeps right out of the thing before I can even insert the magic plunger. Yes, more panic mode. I will say the your folks at Auto Zone in Daly City, CA are very helpful. Although I approached the thought of do it yourself windshield repair with trepidation, the knowledgeable sales person extolled with confidence the efficacy of your product, and its superiority over the kit priced $2 less, while proudly pointing to the 3M label, and the associated 'trusted assurance' of innovation & quality. ROTFLOL! The review before me says it as well, this product does not work.
Don't you realize that windshield repair by a pro is expensive. If you made a "high quality" version of this kit, instead of the equivalent of a toy from the Dollar Store, you could probably sell them for $39.99 and have glowing reviews posted here, instead of a couple of pissed off do-it-your-selfers!
I am not going to boycott 3M as a result. I actually like 3M products and use them often. This is FEEDBACK. Please use it in some way, or EOL this product now.
Do not buy...seriously flawed product and process
This product does not work. In addition, it says it can be used for multiple projects. What? Once the resin has set up in the eyedropper tube and in the application tool, forget it. Curtains for the whole kit. Cheaply made and impossible to properly administer. What a waste of time and money. Spend your money and have a windshield shop, or one of those 'on the side of the road' chip repair places, do the job.
