It's already 110+ out here in Phoenix, and yesterday my girl notices that I've got a corner of the headliner hanging down at the top of the rear window. 2 hours later, I notice the OTHER corner is now down. Sheesh! I've already replaced my A-pillar covers, that were peeling badly at the bottom when I bought the car in April. What's the best spray glue stuff to tack the back corners back up? Any special technique? Hopefully whatever I use can handle the brutal Phoenix heat.
