My XX7 HQ Sandman van

[Valencia]

No. It's all electroplating and the process doesn't effect rubber. That said, you won't get any plating under the rubber either.
Also worth noting is to get a shine on nickel, chrome, copper or brass the steel needs to be linished and polished and this is where damage can be done to the rubber if caught by the belts or mop.

Yeah. I have gas struts on the WB and it's so simple to open and close with one hand. The originals can be a pain for sure, especially when wearing out.
