Wow, there's definitely still some controversy on this subject. As always.
As I have said before, I'm unimpressed by any "dry out" technique or product. IMO, nothing works good enough or safe enough.
The Drystar absolutely does NOT work in 30 seconds unless it's a simple clean bullseye or small chip, then maybe. Anything else takes much longer, more heat cycles.
Also, I don't believe dryout solutions pose any real problems for the repair, unless perhaps there is a lot of the solution still in the break when the repair is done. After it evaporates I think it's fine and I haven't seen any problems from it, even acetone or alcohol. I like the pac men comment though... and in general i would rather not use a soution. But sometimes it's the best bet to get results.
I use a Drystar and the similar coke-can one from LR, as well as various other heat sources like mini torches. I have used several different dry-out solutions. It's all we've got unfortunately.
And heat can crack out a windshield when you least suspect it. Sooner or later it will happen. You just hope when that day comes it's not a job that will screw you bad...
Oh, btw, I also sometimes use vacuum in addition to other techiniques. Use a mighty vac hand pump with a suction cup over the chip and pull a strong vacuum. Let it sit several minutes while I do another car... it can really help. Anyone else find good results using vacuum?
