Hp273 Valve covers back from Leanna

Learn something new everyday! I thought that those fins were rivited on. I wish you would have told me that about 7 years ago when I was polishing mine (plus the entire valve cover) under a thin wheel. That would have saved me a headache.
I bought a quart of plasti-dip at Northern Hydraulics years ago. I just keep dropping ball bearings into the can as I use it, to to keep the air out so it won't harden. I filled a 1.5 x 2 inch bottle cap with the Plasti-dip and dipped them in that. I used a staple box to dip the long one. It worked great with one coat.
