Got it. My post was done yesterday, so we've been communicating after that.
Incase this helps anyone, I've been in continuous touch with the poster (Saad Piracha) regarding some of the 3M items posted above. As per my communication, I've found him legit, he has been very prompt and helpful in responding to all sorts of questions (and i had a lot of them). I've bitten the bullet and in process of placing a small order, I will keep this thread posted once I receive the products and after I've tried them out.
@piracha78 , For everyones help, sharing actual pics of the products (like you sent me) would also be helpful for people. The bottles seem genuine when compared with other pics on the internet ( ofcourse can't say for whats inside unless i get those in hand
