So I am having the Teggy repainted after 27 years, many of those years it was garaged, but the past couple of years, my baby has been outside. Anyways, I am writing this topic for Integra owners to be aware of rust forming under the rear glass of the hatch. You might want to pull off the cover of the hatch to do an inspection, because there was no visible signs from the outside. The body shop only found this after pulling the glass.
That sucks. 
These cars (like most Japanese imports) rust so easily.
They also rust out at the Acura emblem after the gaskets deteriorate under the spoiler mounts. Another spot that I have seen where rust starts is under the bottom quarter glass trim.
