Ok guys sorry but im gonna have to cancel this project forever.
I finally found a hobby store near by that has almost everything i'm looking for, so the model that i'm working on (lotus esprit from about 6 years
) will turn out good, i'm tuning it, but this time with real putty, styreen paper, primer and finally, paint
I'll start up a thread after I finish it. Thanks for commenting so far on this thread, sorry for the dissapointment.
