[splitpit]

I kind of see it like this. By curing you windshield repair resin first and then going back and curing pit resin over it, it's kind of like pouring a concrete slab and allowing it to dry and then pouring a second layer of concrete over it and allowing it to dry, with the expectation that those two slabs of concrete will stay bonded togther. Over time, especially as they age or are driven over (wiper blades) they are not going to hold up well.
