I am not so sure about that. I remember making tons of money back in the early 80's with a can of stuff that dried out points distributors. I waited across the big puddle at the intersection and was getting $10-$20 for each start up. LMAO, I'd say $20, I can get you going. I'd ask if it was their lunch money or all they had, and settled for $10 many times. But a helluva lot cheaper than a tow truck and days missed wages at work. I never did let anyone know what was in the can since I painted it black so noone knew my secret.
But now this new car, my daughter was in an accident. And obviouusly noone noticed the fender hit the coil and broke the plastic coil housing during the wreck. So she had the car back from repair for 2 days, then it started raining like hell on her way home from work. Hit a dip with puddled water, and the car died. So it actually was a direct result of the car accident, it just got overlooked.
