I have one of these to paint that is nearly an inch deep and is closed at the end. Any tips on how to do this easily ?
I’d have to see what your talking about to maybe be able to help.
OldDog…I’ve painted a couple deep intakes in the past. First I tried pouring a little bottle paint in and kept spinning the part/fuse around to coat the inside…don’t try that…it works, but is messy, takes forever to dry and is probably a waste of paint.
I did mask off an intake and spritzed some flat black from a rattle can…not too heavily as the paint builds up quickly in a blanked-off intake. In my case I needed to have US Navy gray inside the intake to a depth of about half an inch (to scale, that is). I cut a piece of Chart-Pak tape and made a mask barrier a half in…(if your finger will fit inside your part!)…then I brush painted the gray outward to the edge.
When that was coated well enough and quite dry, I packed in some toilet tissue until it was to the level of the Chart-Pak…then air brushed my regular outer scheme. When that was dry and done, I pulled out the tissue with tweezers and pried up the tape with a toothpick.
To the eye…the gray seemed to blend right into the black and gave a sense of the desired depth.
But as the previous post stated…more info is needed to give a definitive answer.

OK, funny my first thought was to pour in some paint and swirl it around[B)]. Here’s what I’m dealing with 
. Although it doesn’t look all that deep from the front it actually extends a far as the back of the nose wheel recess in the next photo. 
It could be painted either a silver or aluminum color or RLM 02. Painting it black would tend to undo the effect that the after market piece corrects on the model itself.
Hi O.D.
Can you cut the end off, paint the innards and blank it off again with a piece of painted Evergreen sheet or something similar ?? Or maybe look in an Artists/Craft shop for a long bristled brush that’d get down inside the recess.
