    Pictures from July 19, 2014 Advanced Class

    Another great day of introducing people to wet sanding and rotary polishing techniques. Following the classroom portion of the day it was time to get into the garage and put practical knowledge to use.

    Here we start with some basic wet sanding by hand.


    Hand sanding on the panel edge, being careful not to go over the edge due to the thinness of the paint on the edge. Remember this rule of thumb: don't sand where you can't buff!


    This panel posed an interesting dilemma: you can see that where we sanded there are two dull sections with a shiny area in the middle. That's because of the body line here, and sanding along it is both dangerous (you're sanding on the high spot) and it leaves a very non-uniform finish (the shiny area that the sandpaper didn't touch).


    Coming back at the contour with short strokes, but using the exact same piece of sandpaper and backing pad, yields a much different result..........


    Look closely and you'll see a uniformly sanded area next to the problem area. A little change up in technique is all it took to get the desired results.


    On a different panel, a quick example of light sanding (2500 grit here) and how it only starts cutting on the tops of the orange peel texture.


    Looking closely at the sanded area, you can see shiny spots (a mottled appearance) that indicates our sanding media has only touched the tops of the texture, leaving shiny areas in the low points of that texture.


    Continued sanding will level the paint.


    A quick cross cutting motion with the sand paper (whether a finer grit or the same grit as previously used, if that previous cut was with a very fine grit).


    Flattened texture, but still some gloss due to fine grit of the final sanding process.


    DA sanding back on the hood. We started with 1500 grit and finished with 3000 grit.





    Rotary compounding comes next, but make sure your pad is clean before you start!


    Picking up the bead of M105.


    Compounded area, showing gloss once again after removal of sanding marks.


    Working the wool pad into the tighter contour on the side of the hood.


    After the demos it was time for the students to try their hand (no pun intended) at all of these processes. Here, the hand is flat on the backing pad, the pad is angled and the strokes are short and tightly spaced. Beautiful!!


    Look at Huan, on the right, using his fingers as a guide to keep him from sanding off the edge of the panel.

    Really like the rule of thumb, "don't sand where you can't buff."

    I must admit, never thought about it in those terms.

    It's such an important concept, too. A few years ago I had the opportunity to work with Kevin Brown and our own Jason Rose on a project and we found sanding marks next to a lot of trim and accessory parts on the car. They had been there for years, mostly because nobody had ever figured out how to buff right up to the edge of things like side indicator lights, rain gutters, etc. We were using the DA Microfiber Correction System, which was very new at the time, and found that with this system we could in fact buff right up against the edge of those things and remove those old legacy sanding marks.

    @Selectchoice. You're right, just look at Avalencia getting ready to swing a sledgehammer/use a rotary for the 1st time..



    It didn't take long for him to get his gameface on..



    And thanks to Senor Stoops showing us how it's done, Avalencia [and the rest of us] went from rotary rookie, to producing a swirl free finish without even burning through the paint or anything. Lol.
    Good times

    Wait, here's the moment where he realized he did pretty darn good for a 1st timer.
