i have not been modelling for long and was just wandering about the best way to dry brush and weathering any help would be much appreciated thanks.

We could go on for days about weathering techniques. Truth is there are probably as many slightly different techniques as there are modelers.
This should help get you started..... https://armorama.kitmaker.net//features/60

Check out these articles and come back with your questions and remember.....Too little is way better than too much, nothing looks worse than an over-weathered model. When you think one more bit will be perfect...STOP, it's done.

Thanks Grifter for the help looks like i have a bit of reading to do...cheers

Crossfire,
Reading all the info you can find will really help. But the thing that you need to do after your reading is get an old model and experiment. You can't expect to get good results right away, because you probably won't (I know I sure didn't!)

Practice makes perfect!

Thanks Kent, i have an old model i have been doing a bit of a wash on and i think im getting it kind off but im not to sure about the dry brushing yet ( how to do it etc. ) a bit of pactice goes i long way i hope ..cheers

thanks for all the help guys
