I hope it is okay to post some of my progress here. I was inspired by your work so I hope it's okay.
Aside from weathering my "Hasbo Studio Scale" 12" Speederbike and B wing I have zero experience in weathering a ship.
My plan was to completely finish my Old MPC Falcon first to develop my skills. Then my Hasbro 28" Falcon. Once those were done and I was happy I would then start on the Deago.
Well I said screw it and started on the Deago yesterday.
I am always having to wait to get this special paint, or this special glue, etc. and all that stuff adds up fast.
So,...again I said screw it and used my regular supeglue and my $1.50 black craft paint from Walmart.
This is my first attempt. I am very happy with the pit. Need to add in a little rust, detail, etc.
The hull I am going to re-do in Tamiya Insignia white but I think for my first try this section came out pretty good.
The fun of this is since the Falcon is so messed up you can just go at it again and again.
The pit and weathering streaks, wash, etc. was done with the above mentioned paint, some regular old brushes, a lot of Q tips, paper towels and a spray bottle of water.
I hope you like it.
I used this pic as a reference. It's the bottom of the ESB 32" Filming model.
Mine. I just did the streaking to the right of the pit.
