question for JJ

I'm looking at my shiny black carbon wings and other parts and getting
ready to start sanding to prep for spraying on primer.

Question: what grade of sand paper do I use to break the glaze and
give tooth without removing precious material..................

and..............what to use to remove sanding dust,
etc...........prior to spraying primer.

it's getting closer!

thanks,
Brad

Hi Brad,
I'd sand with 80 grit (dry) on an 18" air-board, if you have one or an
18" hand board with 45 left/45 right action with the board held
parallel to span.
I'd put on a mask, turn on the fans and blow off the surface before
priming.
I use PCL Polyprimer (907 white) catilized with 2% MEKP.
Hope this helps,
JJ

Sam.............an air board is a pneumatic tool that takes the arm
work out of sanding, but they are thirsty and require a beefy
compressor. At least the one I own does.

******************
Often called a straight line sander. They take a bunch of air, like he
said. You need a 220 volt 5 HP compressor at a minimum, or you will spend a
bunch of time waiting for air to build back up. As a general rule, the more
expensive ones use less air, as they are generally more efficient.

There is a relatively cheap one at Northern,

I do not own this, so I do not know how much air it uses.

They do take a lot of work out of sanding things like wings, and prevent
wavy-ness that would happen if you used something like a random orbital
sander.

Blow out really well so that Mr Pinhole is fully exposed on first fill
pass. You don't want to bridge over dust filled holes. They will bite
you in the ass. When they show up, squegee in spot fill before doing
your first sanding. With luck, youll get 90% on first cycle- then 90%
on second.
Good luck

yup, there are lot's of pinholes................I will do my best to
prep properly for them. plan is to spray primer/filler, then make up a
light slurry of primer/filler/micro and squeegee that onto the wing
after the first pass has tacked up.
