Just as a clarification to your post re: color, Interlux Interprotect 3000 has always been produced in a white color. Interprotect 2000 is grey, but has recently introduced a white option.

I don't have lots of experience with barrier coats, but on my last boat - Interprotect 3000 was sprayed on the repaired hull. The final effect was a very hard and smooth, white epoxy - simulating a dull finish gel coat.

I do believe that most, if not all, epoxy barrier coats are distinguished by these similar characteristics, in contrast to anti-fouling paints. The surface is very hard, unlike the flaky layers shown in your photos. Be careful sanding however, if you're too aggressive, it's easy to sand through the epoxy.
