I believe you, but how do you know this?

Gotta watch out though, the other extreme are kiddies who know nothing but run around spewing crap from their mouths. I once read someone suggest using hardware store washers to space rims......

Good friend/fellow rotary car shop owner years ago couldn't figure out why one car, flat out race car, needed rebuilds ever year from coolant seals just disolving. He found out that the owner would go home and put water wetter in the cooling system. So he went ahead and took a few coolant seals and put them in water, strait green antifreeze, dexcool antifreeze, and strait water wetter. He told me that withen 20 minutes the seals in the water wetter were disolving and turning stringy. Mystery solved.

I also bought a parts car once that was running on one rotor. Owner thought that the rear rotor was toast. Comp was fine, but the jacket rotted out a little and a section of the coolant seal was just gone. I knew the guy, knew the car, knew that he had put water wetter in the car after a mutual friend with a 500AWD eclipse used it after he started having issues. Eclipse was fine, few weeks later he thought he fragged the engine. Used iron from my collection and I had another good engine. It clicked years later when I found out about the water wetter. I always just thought that the seal broke loose but the seal itself was rubbery/stringy disolving
