Repairing Inflatable Pin Holes, Punctures, and Tears

In this video I demonstrate how to repair a set of pin holes, a puncture, a seam split on an inflatable pool toy. I use cotton balls and rubbing alcohol to clean the spots before repairing them. Then I uses rounded patches of vinyl and a Methyl Ethyl Ketone (MEK) based glue to bond the patch to the toy. Specifically I am using HH-66 brand of vinyl cement. Please comment below. Any suggestions or corrections are completely welcome.
