Are you not worried about the potentially adverse reactions between rubber/plastic components and a petroleum based product? It probably wouldn't hurt anything in the short term, but long term exposure could cause crumbling, swelling, distortion of bushings/other rubber parts etc. I've definitely seem that happen and have caused it myself before I became attuned to it and now try to avoid direct contact.

"What...me worry?"

Concerned. Yes. On a couple prior vehicles I was lubing rubber bushings w/ DOT5 brake fluid. (Silicone) Here my thinking was that silicone sprays had other stuff besides silicone in the formula that could hurt "rubber." Results? Don't know for sure.

Don't know what's in it and just went w/ Corrosion Block because of what was on their web site. Marketing towards spraying everything under the covers of outboard motors used in salt water...which includes wiring, etc. Main purpose for me was rustproofing w/o hurting wiring, electronics and rubber tubing...notice some some of this around Yaris fuel tank.

An experiment. Stuff doesn't smell bad...sort of interesting, actually.

It's probably great stuff for rustproofing. I've been trying to nail down a strange rumble I get when my '08 hits dips on the highway. I found a crumbling trailing arm bushing and I had inadvertently hit it a few times with oil-based goop. The core of the bushing is solid, but I pulled off chunks of the bits of rubber that extend to outer part of the bushing. I'm just a little cautious now, I guess. Also, in the past, I ruined a few door gaskets as the thin oil-based stuff I used dripped down, swelling them.
