Not great. The headlights start turning yellow after like 6 months. I just did a set a few weeks ago and it already started to haze over. I’m doing everything perfectly and it seems not to be holding up as well.

it has weaknesses that the old provac standard is better at. Can't get enough downward pressure with pit adapter to prevent leaks, uses 3 xs more resin than provac standard. Does seem to have more vacuum. Not living up to expectations. Have been in windshield repair business 34 years and have been with Glasweld all the way.

I like MB18 better. The gray doesn’t weather well. So the amount of tint has been cut so they don’t hide as well from the start. Gw resin is good. I’m just using other stuff more. I have 2 zooms and I have done 3-4 repairs with them in 3-4 weeks. They don’t even sit in the tray now but loose in the bottom of my kit. I have been disappointed with Gw and the products.

Item works great. Expensive though. It would be nice if there was an option to buy more in bulk for a less expensive price.

Se acaba pronto la pila. Se tiene que recargar diario, a diferencia de otras marcas, para que no deje de funcionar de un momento a otro. Es buen complemento del Provac zoom pero con poco tiempo de pila.

Truck Window had Acid Rain like Track Build up. Front real bad in early morning dew. Hard to see out Front Window. Product Removed like 90% of in one application. But left me a White translucent Film on the glass that hard to get off. Guess we need a cleaner for the clean. My Window condition is much better but yet not perfect,

I've got this product based on what I heard about it. I need to say it is not an aggressive glass polish as yo be able to removing scratches/acid etching on the windshield. I've tried it by hand, with 0000 steel wool and also with dual action polisher with glass polishing pad with out the success! Although I need to say it is capable of removing some softer water spots effectively.
