It was that new WD40 penetrating spray to loosen the corrosion on the metal zippers.  I'll silicone spray to lube.
It's going to take a good month of stabbing at it little by little cleaning to get it spotless.  It took me months to get my H180 perfect and at least 2 months to get my Stingray to a point where every nook, crack, and anything was flawless.  Kinda fun actually.  Once it's that clean it's very easy to maintain even tied to a dock.  I'm headed to the fabric store now to get some yards of microsuede to recover the interior cushions in navy blue.  Being a VP guy I'm actually shocked on how smooth this base model engine package is.  I already ripped down the interior headliner and reglued it, it was sagging in a few places.  
Rain?  No problem!  I can't say it enough, it's so nice to be in a real boat again.  Nobody ever ever ever ever buy a Stingray.
