How to cut holes in masking tape?

[belfry]

My ceramic brake disks have some rust developing on the nuts around the fixing points. The nuts are one time use so I'd like to be able to coat them with some inhibitor by spraying them in-situ.

Is there a way to cut clean holes in masking tape? the nuts are about 10mm wide and there are lots of them in total. I'd rather not cut each hole out with nail scissors!

I acknowledge that I'm being OCD but I'd still like to try.

Spray inhibitor into a cap, dip very fine brush into it and apply to nuts in situ.

I would use a small wire brush and get the corrosion off. Then use a small paint brush to brush on any inhibitor. Bilt hamber rust remover would be good too.

If you need to make holes in masking tape then I imagine you could just use a hole punch.

Squirt some inhibitor into a container - the cap of the aerosol will do.
Apply to nuts with a brush.

You could try masking up near to the nuts, then use masking fluid, it's thin, quick drying, easy to peel off and cheap. The Windsor and Newton one is a lot cheaper than the humbrol one. From your local art/ craft shop.

I wouldn't be spraying anything like that, near to exposed braking surfaces. If it REALLY bothers you what about a little rub with some wire wool and then a wipe with a rag that has some sort of inhibitor on it? Not enough to fling off obviously.

I'd clean them up with a small wire brush and then brush paint with Bilt Hamber Electrox.
As the cured film is 90% zinc it may survive high temperatures. Worth a try?

Hand paint with a small brush with an engine enamel or clean up and use bilt hamber atom mac regularly to see if it keeps it at bay.

Thanks for everyone's replies. I ended up using a soft wire brush on a Dremmel to clean the surface, then I applied Cerakote Ceramic Coating which will withstand high temperatures.

Looks better.

Now, about that tatty yellow caliper.........

Looks like the Dremel relocated the corrosion from the nuts to the calliper.

The callipers were dirty before. The dremmel only removed a microscopic amount of surface material. It did provide a good key for the ceramic coating though.

I will get the calipers cleaned over the weekend!
