Day 1 - Morning Session - Extreme Prep Wash
This class had a VERY RARE OPPORTUNITY - and that is they get to work on a Barn Find with severely stained and oxidized single stage paint. So the first thing the class is going to learn how to do is the
Comet Wash Technique.
NOTE: This is ONLY for old-school, solvent-evaporation single stage paints like lacquers and enamels.
DO NOT USE THIS TECHNIQUE ON A MODERN CLEARCOAT FINISH.
BEFORE CONDITION
First, lets photo-document the BEFORE condition. Notice the overall dull, chalking looking oxidized paint and also look at the huge STAIN in the middle of the hood. There was also a similar stain on the trunk lid.
For what it's worth, while I've had a LOT of cool cars go through my classes in my lifetime, this is the first time I've had a 1958 Chevy Bel Air.
EXTREME PREP WASH
I have always taught folks to start at the bottom, and then go to the top. It has to do with avoiding water spots on the paint.
Machine Scrubbing Tires
Nothing wrong with working old-school style by working by hand with a tire scrubbing brush, but I already have around 20 cordless FLEX PE-150 Rotary Polishers and what we do is attach a 5" backing plate and then to this, we attach a 5" Rotary Brush. Now this is how you get a really dirty tire clean.
The Comet Car Wash Technique - Removing Years of Oxidation During the Wash Process
After wheels and tires, next up the class is going to learn the Comet Wash Technique. Comet has a powdered abrasive in it plus some bleach to clean, brighten and also sanitize. The way this works is after giving the car a good rinse to remove any loose dirt and/or dust, next you spread Comet over the horizontal panels and then wash them with your wash mitt. For verticle panels, you pour some Coment directly onto the face of the wash mitt and then wash these panels.
The abrasives in the Comet, plus the rubbing of the mitt over the oxidized paint, gently exfoliates or abrades-off the dead, chalky, oxidized paint to reveal paint that is now clean and shiny, and PERFECT for the next step, which in this case will be rotary polishers with wool pads.
