I have a small leak in radiator that requires me to put water in every 4 or 5 daysWhat's best sealer to use that I don't have to worry about plugging up system?
The safest way is to take it to a dry cleaner.
Most of the caveats that apply to raw wool will still apply to wool fabricUse cold water, hand wash, and avoid rubbing the fibers togetherI would use a very gentle soap, and as little as possible.
go to the parts store and get a tube of aluminum seal and follow the directions.
