When I did my Subie conversion 3 years ago, the shop managed to swap my fairly pristine Engine Lid with a crappy one.  Ugh...but I guess with a busy shop things like this happen.  So the one I've got now is kinda crusty.  Drops fragments of crusty foam onto my engine.  I'd like to fix/improve.  One idea I have is to use the acrylic deck coating (from Home Depot) I used to rejuvenate my upstairs deck in my condo; it's "rubbery"....i.e. flexible...and surely can withstand heat.  The stuff I have is tan in color; I guess that's OK....black would be better (I could use the brush-on tan acrylic deck coating, and then add a rattle can coating of flat black spray paint).  Mostly, I want something that will hold the foam together and stop the debris from falling down on my motor.  Ideas?
