Canopies

[Leigh]

Right well after finally figuring out how to mask canopies, I've still got one issue with them before I'm happy with them.
DUST

I always seem to get crap stuck to the inside of a closed canopy.
Here's wot I do, double dip my canopies in future allow plenty of time to cure
check for flaws and dust stuck to them then mask them
Clean the inside again with a moist Q-tip
dust out the cockpit with a make up brush from every angle, while tapping it around to loosen any crap out from the fuselage/cowling
blow it out with one of those little bulb blowers used for getting snot out of babies noses
dust again
run a sponge make up applicator around in there to grab anything left
glue on canopy
and it never fails when I pull off the masking tape there's flecks of styrene or summat stuck to the inside of the canopy that won't tap off.

What do you guys do?
Put the canopy on after paint and if so how do you mask your cockpits, especially those that have one piece canopies?

Well, if there are any openings left (e.g. jet nozzles), you could slide a compressor hose into the aircraft and try to blow away the dust.

Are you sure its dust?  It sounds like a particle or two of paint that has snuck its way through a small gap somewhere.  I often have the same problem  

One solution is to put some tissue paper inside your canopy, which you then just tack onto the airframe with something like white glue whilst you spray.  The tissue catches any paint that sneaks through.
