NoOx compound required per county

The county is requiring me to put some No Ox on my connections (200 amp service with mobile home feeder--aluminum). Just wondering how much to use and if it can have any negative effects. I've used it before, but just on my car battery and ground rod connections.

Enough to cover bare aluminum is how much you need. Putting little more than you need will not hurt as long as it is not enough to drip.
There won't be any negative effect as long as connection is good and tight. If there is over heating or arcing, it probably will burn or catch fire easier than without, but that shouldn't happen in the first place.

The no-ox should have instructions on application. Usually needs to be worked in using a brush. Plus the bare conductor ends should be wire brushed to be cleaned before application.

You are basically applying a thin coating to insulate the aluminum wiring from the air to reduce oxidization.

Are these connections already made? If so, you will not be able to get the compound into the lug without killing power, possibly involving the power company and putting new ends in the lugs.
