Brian,

Actually I've also used the tire foam for a short period of time in the past but with mixed results and a few concerns.

My results included a near perfect engine bay immediately after application with all rubber and plastics looking as new. However I also noticed excessive dust buildup due to the tire spray which meant cleaning more often. This was 10 years ago BTW so I don't know how the new sprays compare.

The two concerns I had include the worry that the tire spray may contain oil based silicone as part of it's ingredients (which would deteriorate rubber Like Armorall) and how it would affect the belts (Slippage?)

If you've been using them for an extended periods have you noticed any browing of the rubber components? Also do the new tire sprays dry completely to the touch or do they still feel oily?

Thanks for your help, always looking for better ways of keeping the car perfect.
