So you are okay with your supplier (who can sell the materials for probably half your cost) directly competing with you?
Dont get me wrong. We still use 3M as well, sometimes it is simply the best material for the job and some jobs it is specified. I'm not going to stop using it but we also use probably more Oracal 3751 as well nowadays too.
On the 480 film which is the subject. Cannot say I've talked with anyone who has used it yet. I just dont see the appeal of spending so much more for the product when other products work perfectly fine at much less cost. How do you pitch that to a customer, "we would like to suggest this new material, it's unproven and really offers no realistic advantages for you the end customer but it's about 50% more expensive". Yeah that will fly....
