I think you're partially correct on the secrecy thing. There were a lot of old timer guys out there that wouldnt want to help you out at all. Mostly because they didn't want to train you and then you turn around and take a bite out of their business. thats definitely how it was where i was from and I've heard others say the same thing. on the plus side, those old timer guys are pretty much retiring or sticking to just the bread and butter jobs. with sources such as this forum, and social media like instagram, theres a vast amount of trimmers out there that will tell you a lot of stuff to help. now they won't give away their deepest darkest secrets and tricks unless your dedicated to working for them, and understandably so. but they will help you out and give you the tips and tricks that you can use to become a better trimmer. and then from there you can start to experiment and try your own new things. ALSO.... sids dvds on upholstery, will immediately take your work to the next level. so if you haven't ordered a set of those yet, i suggest you do.

That dash looks awesome in there!
