Nope. This was in the early '80s.. I didn't think of it at the time. I still have the block warmer cord that was tied up near the radiator.... It's somewhere in the garage...
1969 I was motorcycle ice racing. Around here the rules would not allow spiked tires, only tractionized, aka roughed up on a special grinder. The course had sand spread on the start/finish line and in the corners, rest was just ice. The gas station I worked at had several cans of AC Liquid Tire Chain on the shelf, I bought a couple of those cans and another guy who I worked with and also raced with tried it on our tires. It didn't really help though. We were protested by some other racers but nothing in the rules prohibited spray on substances, at least for that season. By the next season the rules addressed and prohibited that spray.
That's a pretty damn good idea, tell ya the truth. Washing the road salt off the undercarriage is just about impossible any other way.
...I seem to remember a photo in a magazine of a '54 Ford home from Bonneville. It was up on 4 jack stands with a sprinkler positioned under it to wash off the salt. Wish I could find that image.
........I usually just get caught in a torrential downpour, not like I plan it that way, just seems to happen.
Most car wash places here do have undercarriage sprays for extra $. But I believe the water is recycled. ( salty )
when i was a kid my dad jacked up the right rear "drive wheel" of his chevy van ,started it in gear and fed black wallnuts between the tire and a piece of plywood to peel off the husks so he could dry and crack them. worked like a charm !
Yeah, it happens to me also... I walk outside on a gloomy day to cut the lawn and it starts to rain..... It's happened more than once...
