Just Sharing This Brake Master Cylinder Trick

As long as the reservoir is sealed (it IS sealed, right?) the inside shouldn't rust.

I did paint the outside of my MC when I converted to DOT 5, and it's still real purdy after 7 years.

I bought out 4 different Advance Auto stores of DOT 5 fluid when they were on sale "buy one, get one 50% off" and now have a whole shelf full of it, more than enough to do my next 2 project cars.

...and I haven't needed to add any to the original conversion.
