Fix-A-Leak, from Marlig Industries, with offices in Niagara Falls, N. Y., is a blended concentrated material designed to seal leaks in virtually any material. It can be applied for leaks in a pool shell and works equally well in plumbing.

Fix-A-Leak will form a permanent seal on holes 1/8- in. diameter. Use one quart per pool up to 22,000 gallons. Do not use in excess of one quart per 5,000 gallons of water.

Fix-A-Leak has been field-tested under various weather conditions and proven to be effective in sealing leaks. It is also an excellent preventative maintenance aid, as it coats all surfaces that it comes into contact with, cutting down on the formation of rust and corrosion.
