C150 question

Hope this is the right place for this question
I recently took out that fabulous french C150 http://www.fs-tutorials.com/en/down_planes.php Its amasing! one of the best modeled AC I've come accross! One thing about it that annoys me is that the glass from inside seems way to scratched and crazed, although this is quite realistic I find it to be to much and it makes the outside FS world look a little dull and colourless.
My question is, can some tell me how to change this glass effect for something a little less......disruptive ;)
cheers

PS. if you havent tried this little gem.....you should. especially if you are new to flight sim or flying in general. this is a great trainer, real world and in FS.
