Hydraulic reservoir

[Bruce Parker (RIP)]

What would be the appropriate way to line the inside of a hydraulic reservoir tank? Would de-rusting and a POR type finish work or is it best left untreated steel?

Assuming this is for hydraulic oil and not brake fluid. I would not use any coating in the tank for fear of particles getting into the hydraulic system.

It's a hydraulic clutch but the same as a brake fluid system. I assume the inside of a reservoir is uncoated steel (plastic in the modern era) which would require the vehicle to slosh it around the unfilled part at the top regularly preventing rust. Then we have our old beasts that don't run as often as they should which is why I wonder about a coating which the brake fluid won't dissolve.

Hi
The problem with brake fluid is that it can absorb moisture. I have no idea what type coating would be resistant to brake fluid.

You would think that POR's caliper paint https://www.por15.com/POR-15-Caliper-Paint should be at least somewhat brake fluid resistant but the web page is clearer on its temperature resistance than how it will perform when continuously in contact with brake fluid. I suggest it would be fair to ask the manufacturer how well their product would perform in these conditions.

What about the use of a silicone fluid? Would this help you bypass the obstacle?
