Id go with cheesecloth, Its not expensive and The results are quite good.
heres what I do:
1. cut cheesecloth to specific size and then dryfit to make sure it will cover where I want it to.
2. dip it in the white glue-water mixture
3. apply it to the model
when its dry I carefully take it off and spray paint it- or airbrush
4. If you are carefull when painting the cloth will hold its shape, so then you can just reapply tho the model with small dabs of white glue in key places.
heres what I got.
