Is Moroso A-B epoxy good stuff? Anything better?

Here is are some stock intake ports. I was just looking at the above pics, and I noticed how wavy the bottom of the port entrance is. I was showing my son how the dremel works (I used it with some sanding rolls to smooth the epoxy, which is perfectly level even though the pic doesn't look like it. Friggin pictures are bringin me down...) and I should have been watching a little more closely.
