The poly patch kit (not shown) is ideal for repairing pinholes, hairline cracks and holes up to 1/2" in diameter. This kit should NOT be used to repair a tank that is used for drinking water.  For best results, surface to be repaired should be above 32 degrees F. The kit consists of epoxy, a small brush to apply the epoxy, a small piece of sandpaper to "roughen" the area to be patched, a piece of mastic to temporarily fill the hole/crack and a piece of fiberglass.

Instructions for use:

1. Drain tank or rub the enclosed mastic in hole to temporarily stop leak. 
2. Sand area about 1" around hole, remove dust and wipe clean. 
3. Cut fiberglass cloth to cover sanded area. 
4. WARNING: Mix repair epoxy as follows - work quickly as mixed epoxy will start to harden in only 
        6-8 minutes.
        a. Firmly apply pressure to lower half of pouch to burst center seam.
        b. Mix contents thoroughly BUT NOT MORE THAN 2 MINUTES.
 Cut pouch open and apply 1/2 of epoxy mix over damaged area with enclosed brush. 
6. Place fiberglass reinforcing patch on epoxy and cover with remaining epoxy mix. Taper and              smooth edges. 
7. Wait at least 20 minutes or until patch is tack free before refilling tank.
