I've had good results on engine casings using this stuff but along with their etching primer.

One would imagine brake caliper paint is resistant against brake fluid.
It's mentioned here: https://www.nonpaints.com/en/vht-calipe ... in-aerosol
I'm guessing you can find VHT paint in Australia.
It's best to heat up the part first or bake the paint in later.

I've always used black (epoxy) garage floor paint (here referred to as liquid plastic) for axle and suspension parts of my cars. That stuff is resistant against almost everything and holds up really well. It's thick though and can't be sprayed so nothing for your clutch cover.

Hi,

A 2K paint should do the trick (the most chemical resistant paints).
In Australia you could use Eastwood 2K Aero Spray HT Engine Paint Gloss Black.

But be a little careful with brake fluid (that's really aggressive stuf).
If you spil it flush it immediately with water to prevent it from damaging the paint.

Good luck!

for $132 for a can of primer and paint you can almost get a spare clutch cover.
Another option would be to clean out the complete clutch system thoroughly and go for DOT5.

Gerhard, Australian dollars are not US dollars....

Also: it's an example: just more or less any 2K paint will do the trick (clutch cover will become maybe 125 celcius/260 fahrenheit max. I assume and all 2K can take that).
Eastwood is just a well known brand in the USA for cars & motorcyle restauration projects.

I have used VHT since years (40 or so) but lately I discovered that they are not really fuel resistant (although they say it should - and in the past it did!).
So for me. either powder coat or 2K if you want fuel- and a little brake fluid resistance …

I know it'S AUD. It's still 80 Euros for 2 cans of spray paint.

another option to fix the problem for good would be polishing the cover.

Now there's a thought, that's something I can do, have you seen this done on one of these, I might give it a crack, nothing to lose really if it looks wrong just paint it

Here I've a little relief in the paint (difficult to see on this low res. pics), looks nice in reality.
Is powdercoat by the way.

do you think the drilling is the way to go
I don't really have an answer to this.
Fact is those clutch covers are becoming rare so the first question should be: do you really want to drill holes into it? There's no going back and try to find another one. They do exist and sometimes prices are reasonable but that's not often.
You will notice after a short ride that the closed clutch cover gets really hot. The vented one has a clear benefit. Also it will blow the dust out. In the end this will probably make your clutch last longer.
On the other side the clutch noise/rattling will be louder. Also after a while you'll probably notice some surface rust on parts like the springs which now you'll be able to see.
That's specially if you live in a wetter climate or if the bike is parked for a longer while. These two things could also lead to the clutch pack getting stuck together. But for that the bike will probably have to be in storage for several months or even longer.

If you just want to get some dirt and heat out you can install a washer between engine and clutch cover so you have a little gap. (A washer - not a spacer). The way of the piston is long enough so that the added washer won't be a problem.

Just like Frank, I do have both (also powdercoated black) :truck:
