Anybody got experience in DIY painting valve cover.

Because my car is going in workshop tomorrow. Most probably they gonna dig the engine out. So I was thinking I drop by the shop some day and spray my valve cover. I do not plan on removing the valve cover because I just replaced the valve cover seal recently. Don't want to break it. SO I actually planned to cover the surrounding with newspaper and spray it.

But... Any advice on the type of spray paint that can withstand heat?

And...
