Thanks for the compliment !
I am almost done can post finished tower tomorrow I hope.
I am a novice at this and do not have an air brush so I used a variety of items and techniques:
I took the tower partially apart, taking the tower off the base and roof off.
I over-sprayed everything with ModelMaster Flat, Dulcote can be used too. I did that because I use a lot of powders . I gave the tower partial wash using diluted Woodland Scenics Black 1220, then applied Doc O Brien's weathering powders with pad and fingers ! Also used Pan Pastels and Testor's Rust pen. The wood supports were base painted with Floquil roof brown. I over-sprayed, lightly, from a distance to seal the work as I went along.
I used Woodland scenics scenery glue on base and covered it with ballast. After that set I used wet water and more diluted scenic glue to set the base. Today I applied some powders to darken the ballast and added some weeds.
