This makes about as much sense as seeing a "refurbished/rebuilt" vacuum tube for an old radio or television. Even if the diaphragm isn't ruptured, I can't believe that it'll last any length of time before rupturing due to age. Unless they're cutting them open and renewing the diaphragm, I'd stay clear. Just my thoughts.....
I got one of the new electronic regulator valves to replace a leaking aluminum body valve that only lasted about 40k miles.
The new one is doing odd things like switching between cooling and heating while the car is pretty hot. It's as if the system overshoots the cooling temperature and then heats to bring it back down. In cooling mode, it will also start blowing hot air through the side vents and cool air through the center vents as if it was switched to Bi Level.
I don't think I'm getting the same high fan speeds I was automatically getting in Auto Low mode anymore.
Anyone else with the new Climate Contol value with similar experience? Thanks
It might depend on what kind of parts you are treating.
There are many good rust converters that do the same thing, turn soft red rust into hard black. If you use any of these dont wire brush too much old rust off, you have to leave enough for the chemicals to work on. With this product can then be bondo'd over or painted. POR15 or Miracle Paint cant be painted over unless you sand it first. Regular POR15 must be painted, but I think they make a final finish version.
For smaller parts evap-o-rust will clean all rust off down to bare metal and is very non-harsh chemical. Just submerge in liquid for a day or two and it comes out clean.
Reverse electrolysis also removes all rust.
Sealing the rust is second to media blasting or the other rust removal methods that remove all traces of rust.
