Compaing Interlux to International (Micron 66 to Interspeed 640) and primer

[Captain Pappy]

I'm looking for sites that compare Micron 66 paint to Interspeed 640. I've heard only go with Trinadad SR or Micron 66 by a handful of people. I can get a great deal on International's Interspeed 640 and I believe Interlux and International are somehow the same company. If true, is the 640 the same as the 66? As there are so many "Pro" and "Extra" type buzzwords on their products, anyone have a comparison chart of these?

Also, I'm sorting my primer and deciding between the old favorite Interprotect 2000e vs. the newer(?) HS. (the first being a 2 in 1 primer and epoxy filler and the latter just a primer). Someone said HS has Microplates and the 2000 doesn't, but I see they both have it. Experienced users here? Thanks!
