differential gear paint

[gsd2000]

I'm rebuilding a diff very soon and was wondering where I can buy some differential gear paint, so I can read the tooth patterns.

Do you need a gear paint or can you use other alternatives?

Thank you

I assume this is to measure the meshing patterns ?

I use engineers blue

Engineers blue is what you need.

That's perfect thanks

I tried an aerosol blue before....it dried and just stayed there. It wasnt soft/wet enough to actually leave any marks.

Never did get an alternative.

Not sure if all blue's are the same

You get wet fast drying blues that you can cover a surface with then scratch into and grease based ones like that linked above for jobs like checking the mesh on a diff

Red lipstick is good for diff's.
