Hey, everyone, and welcome back.
Tom Cornelius here.
Application engineer at 3M.
In the last video, we began the sanding process
on our body filler.
We did the initial sanding steps, and in this video,
we're going to finish sanding our body
filler using 3M standard operating procedures.

It's important to remember to wear your proper PPE.
You can see today, I'm wearing a pair of protective gloves.
I have a respirator as well as safety glasses.
Another thing to remember is that this video
is recommended for the body shop or paint shop.

please see the link below.
Now that we've completed our initial sanding steps
using grade 80 to 120 abrasives, we're ready to transition
and do fine or abrasive grades, typically a 150 to 180.
Again, we strongly recommend the use of dust extraction
with either a net or paper abrasive.
And further, we want to reapply dry guide coat
on our body filler as we move into these finer sanding
grades.
So hopefully the body filler feels good.
We're getting straight back to contour.
That would be a good transition to move to the finer grades.
Again, we recommend 150 to 180 and the use of dry guide coat,
and we want to continue blocking our body filler
until it feels completely smooth, flat, back to contour.
Overall, it feels good, and we're
confident that we're ready to move to the glaze step.
Once we've completed blocking the body filler,
there's a couple more steps we need
to do before we're ready to move on to glaze.
One of those is going to be to reapply the dry guide
coat to the outer perimeter paint surrounding the body
filler area.
Inevitably, there's sand scratches from the block
out in this painted area, and we need to reapply that dry guide
coat to the paint, and we need to use a grade 180
abrasive on the DA and properly refine and feather
edge all of that surrounding paint
to reduce the chances of any sand scratch swelling
or repair mapping.
After we've completed this step, the next thing that we need
to do, again, is to use either an air blower,
or if we're using a dust extraction system,
we can use the Scotch-Brite Clean and Finish
disk to get rid of any of that dust that
might be on the surface.
And at that point, we need to thoroughly reclean the surface.
A strong recommendation here is that we
apply the VOC-compliant solvent-based cleaner directly
to the paper towel and have a secondary paper towel,
and we want to wipe the body filler with the saturated paper
towel, followed by a wipe with the dry paper towel.
We don't want to apply any cleaning solvent directly
to the body filler.
Body filler can soak this material up like a sponge
and could lead to other issues later.
If this is your standard operation,
it's strongly recommended that you apply dry air
across the body filler to force out
any of that cleaning solvent that may have weeped down deep
or absorbed into the body filler.
Well, hey, guys.
That does it for our body filler sanding.
