I know painting cases is a bit of a no no but I got my case back from being machined today and the acid cleaning has left its mark

Erroded some of the external edges and pitted aswell. Inside is good just the outside looks a bit ordinary.

The way i see i have two options spend some time smoothing the bits you'll see or paint it. I.ve noticed some of the yanks paint their cases gloss black looks good.

I kinda know what the answer will be let me know anyway.
Thanks in advance.....😀

Get some emery paper and smoooooth it out or blend the etched surfaces so there not as noticable.

For years I worked for a VW business in Sydney and my role was reconditioning his engines. He insited that I painted the cases once they were crack tested and linebored. On a good week we could fit 4 engines and send out 1 or 2. Over the years we never had any complaints from people saying their motors were over heating. I have on occasion painted my own motors and having a temp guage fitted to my VW's never seen high temps from my oil. I was fortunate enough to learn through out the years that poorly fitted tin ware was the most common sorce of overheated closley followed by incorrect ingition timming and on rare occasions when none of these problems were present and I had to find an over heating problem I would find that the engines either had a large amount of carbon built up in the combustion chamber or that the engine was simply built with too much static compression.
So in conclusion IF YOU WANT TO PAINT YOUR CASE GO FOR IT.

Each to their own just remember what goes around come around.

i'd paint it. what looks good is good. as long as you keep the grime off it will disperce the heat. and fit your tinware tight around the motor and keep a good seal from tinware to motor.

radiators are painted black because it dissipates heat better.

To summarize the other post, painting the case or the gearbox will not hurt it and will not noticably effect the heat transfer from either.

Trust me, I measured the effect of paint on a cylinder, and it wasn't much. On a case it has even less effect, as it is much cooler.

If you want to paint it, paint it.
