using shaving cream, a banana, and butterspray to remove scratches in a cars paint job?

[ArgonianVoter]

I recently came across a video where someone used a banana, shaving cream, and what I initially thought was cooking oil spray (but now suspect was actually a butter spray) to remove a scratch from car paint.

I believe the mechanism may involve a surface-level interaction between dimethyl silicone (likely PDMS, found in many butter sprays as an anti-foaming agent) and the surfactants in shaving cream. I’ve tested this myself.

I didn’t observe any significant chemical reaction — just minor bubbling, likely from propellant or minor surface disruption. So I suspect this works through a more interfacial or physical effect, where the PDMS fills in micro-scratches or surface pores and alters light reflection, temporarily masking the scratch.

someone please confirm.

Sounds like the sort of thing Garage 54 would do.
