Have you cleaned out your cowl lately?

Blegh! And this is on a southern california car - I don't even want to think about what it'd be like elsewhere.



Figured I ought to clean it out while I'm resealing the heater box and sure am glad I did. Pulled all the fiberglass insulation from under the dash, got the wiper seals all renewed and am going to toss some RAAMmat on the firewall and under the dash before everything goes back in. Whew...sure is looking better already. You guys recommend I spray some rustoleum or something before slapping the deadener on there? Only some very minor surface rust that I can brush off with my hand and will clean everything down w/degreaser. I'm definitely going to test for leaks before the stuff goes up there, too.
