Mine isn't a SE air cleaner but I painted it black and polished all the front edges and it looks almost like the engine now.

 

Looked at ACE hardware, Home Depot, Wally's, and a couple other places, and gave up. Couldn't find "wrinkle" paint anywhere, and went with some Hi Heat BBQ flat black that I already had.
When I got to Autozone, after the fact to order my K&N filter, I saw they had "VHT black wrinkle" for $8.

 

I hit the exposed areas of mine with one of those fat black magic markers. It looks pretty good if I don't say so myself. Cost $0. Needs occasional touch-up but holds up fairly well.

 

Mine was painted by an HD Tech using flat black rattle can paint; looks fine after 2+/20K miles.

 

Sprayed mine with Rustoleum Satin black 2 years ago and no problems yet. Looks much better!!! Only painted outside as I did not want paint going into motor if it decided to peel.

 

VHT high temp valve cover black wrinkle paint from AutoZone, real good match to the motor

 

Yes, painted mine BB-Q black with heat resistant paint.
