Valve cover to do's?

I've wanted to take off my aluminum valve cover, clean it up and put a new gasket in for a while now. It seems easy enough, I assume I can get it done in an hour or so unless I decide to paint it. Couple questions:

- I'm debating painting the valve cover, any special prep required other than cleaning it up and hitting it with an engine primer and then color?

- Is there anything else I should do/inspect while the cover is off?

Then start with using a self etching primer and you'll be good to go

That is probably the most important part of painting aluminum other than degreasing and prepping it first- the etching primer.

I just did this not too long ago. I replaced everything on the valve cover like the ccv elbow and gromet plus the metal fitting on the front. Also replaced the gasket. I just cleaned the valve cover real good and scuffed it up with a red scotchbrite pad and painted it with some duplicolor engine paint. Held up good so far.

A good de-greaser is purple power which can be found at wally world in the auto section or any auto parts store. I just want to say to you WEAR RUBBER GLOVES. I didnt know this the first time I used it, it might even strip some paint off for you.

It will take the moisture out of your skin and prolonged use will dry your skin permanently. I can no longer touch any kind of animal from the ocean after using that stuff for three years with gloves. We used it daily at almost full strength and it messed my hands up. Shrimp, fish, crustaceans, all of them now make my skin dry out, turn red, and then peel off to hurt until new skin grows back. Never had an issue till that stuff and I grew up fishing and surfing the days away so I know I had no issues prior to that.

Use gloves!!! Having to change your past time sucks.

I hit my valve cover with some degreaser, then brake cleaner, then followed that up with a wire wheel on my drill. Gave it a good rinse then sprayed on a few coats of engine enamel. 6 months or so later, paint still looks great.
