For a fill resin my recommendation for all temperatures is our new
Premium Bond 20 Windshield Repair Resin. We just introduced Premium Bond 20 this year and so far the feedback has been overwhelmingly positive.
As with all Delta Kits products we offer a 100% money back guarantee so if you don't like Premium Bond 20 for any reason we'll issue you a full refund or you can exchange it for MagniBond which up until this year would have been my recommendation and is still a favorite among windshield repair technicians worldwide.
For a pit fill resin my recommendation would be
Premium Bond 3000 for all weather conditions. This is also a new product for 2016 that has performed impressively.
A good alternative pit filler for hot weather is Delta Kits Premium Plus Pit Resin and for cooler weather our original Premium Pit Resin is a great choice.
I'm sure you know we have a number of different
windshield repair resin viscosities to choose if you like using different resins for different climates but I always recommend what I use myself and I don't find a need to carry a toolbox full of different resins.
