What are the main reasons Plasti-Mend would fail?
There are basically three reasons for failure: 1. Improper surface preparation. The surface must be clean and dry. It should be cleaned and primed with the Cleaner/Primer. There should be no moisture. If any moisture is on the surface or in the cracks etc., the Plasti-Mend cannot bond to the plastic properly.2. Improper application. The Plasti-mend should be brushed on in a thick coat to allow for the bonding process. There should be at least three coats applied, more for larger or difficult areas of repair. The second coat should be applied 1-4 hours after the first, if possible, to provide more bonding action. Timing is not critical on later coats.3. Evaporation of solvents. The bonding process relies upon the correct amount of solvents in the product when it is applied. If too much of the solvents evaporate and the product becomes too thick, Plasti-Mend will not bond properly. It should be about the consistency of honey when it is applied.
