Re: Training
Actually that is an old method that was used for quite awhile and did a decent repair in most cases. I worked in San Diego as a salesman in 83,84 we had a girl that came by and used what looks like the same system in the video. Current systems use an injector with better pressure and vacume combined with better resins one of the old ways was to use heat more heating up the glass causes a vacume when the glass cools pulling the resin into the chip(Take a glass bottle heat it up put your finger over the top then wrap a iced towel around it you will find you get a suction on your fingertip as the glass cools) one of the downfalls of the old way was lots of heat often would cause an unstable chip to spread(crack out) current methods give a better and easier fill with less stress to the chip making a breakout less likely. If you were a topnotch tech and paid attention back then the repairs looked good but like you 1957 chevy it wasnt as reliable as the 2008 chevy but did the same job
