I'm pretty sure Finaplix brand is still around. If not Component TH is just as good. Some say Component is a cleaner product than Finaplix anyway. I've used both, and had the same results.
They are both still available. However, I think Comp. TH is better anyways, it seems to have a lot less filler/binder in the pellets or sumthin' cuz it filters way frickin' easier.
