The folks at Cypress College in nearby Cypress, CA, have a certification program for Automotive Detailing and Refinishing taught by Ed Terwilliger. For the last few years Ed has been bringing his students down to Meguiar's Garage for a bit of working field trip. Last night Jason Rose gave them a great run down on D/A sanding and rotary buffing as it applies to auto detailing. The students were treated to Jason's incredible depth of knowledge and some hands on time with Meguiar's new Unigrit D/A Sanding & Finishing Discs.
Of course we started off in the classroom for a rundown of the products and processes as well as just a good primer for the fun stuff that would take place later in the garage.
Here Jason is discussing the differences between finishing discs and sanding discs, between leveling paint and removing defects while retaining texture.
Abrasive meets paint.
Now look closely at this: both sides were D/A sanded with a 1500 grit paper, the left side being a 1500 grit finishing disc and the right side a 1500 grit sanding disc. The difference? You can still see the texture, the orange peel, on the left side but the right side has been cut flat. What does that really mean? Just that you can actually sand out scratches and other defects without removing orange peel, thereby retaining uniform texture throughout the finish even when sanding just one panel, or just part of one panel. That way you correct the defects without changing the appearance of the area relative to the rest of the car!
Here you can see three distinct levels of cut provided by, from the upper section working down, 1500 grit sanding, 1500 grit finishing, 3000 grit finishing.
Now Jason breaks out the rotary to pull out the sanding marks and restore the shine to our test panel.
And the shine is back!
Then it was time to turn the students loose on the panels.
Art in sanding slurry.
Pick up that bead!
Ed is a real "hands on" instructor!
Inspecting their work.
We had a great time last night thanks to Ed and his students, all of whom where hungry to learn!
