Hey i am done painting a 1/72 King Tiger and was wondering if i could get some advice on weathering in this scale as thers not much out there about it.
All help is apreciated

Buddy,
There are probably hundreds of books and articles on weathering. Just look at this site, you will see some of the finest modelers in this hobby. Study what they have done, read their techniques.
Typically, a wash of burnt umber followed by dry brushing is all you will need in 1/72nd scale.

There aren't a lot of small scale modellers out there...I have a bunch of things that aren't available in 1/35th scale........and they are cheaper too......good point there.
I finally found a guy that comes to our shows every year with his small scale stuff.....and when i asked him the trick....he said "Be subtle with your weathering."
Sounds simple enough.....I am currently working on a diorama of an M4A4 75mm Sherman of the Ontario Reg't being moved by a Diamond T through Italy....it's from a bunch of pics that were taken of the move. I drybrushed....then did the markings....then did the washes...this way the washes tone down the dry brushing and the markings.
The pictures show a lot of dirt and dust on both vehicles and I found a very fine dust off of a logging road......I'm adding it gradually....and so far so good...Having trouble finding figures for it....and also...there's no glass in the Diamond T's windows...Looking at pics in magazines of small scale stuff....it looks like most leave the windows without glass.....I'm thinking of trying something the airplane guys use called Krystal Clear....liquid that you can make go into small areas that dries clear....kind of like blowing bubbles with a loop....but it dries hard and clear like glass.
When I get it done I'm hoping to get some pics to post here.
Good luck with your project.

I follow one rule. That is to just stop when I am at the point where I feel that it nees just one more touch of this or that. Just before you think it is
done is when it is done. Dont over weather the smaller scale and just suggest a hint of rust or dirt ect. Take your time and work with fine pastel chalk dust
it is hard but it can be done. Good luck.
