Some stuff from Professional Boatbuilder magazine from 1990 in regards to this. They are "not" stupid. And a couple "cut and paste" notes from Walters in the same rag. Enjoy.

For lay-up (skin-out) it is fine, still to this day, but MANY, Eliminator, Cougar, Hustler, HTM, Velocity,Nordic etc still boast about NOT using a chopper gun. It is only for wet out on the first two lay-ups against the gel anyway. ("skin coat") Regardless of who you are, you need to hand lay or vacumm bag your hull. Hand lay is the obvious. What is important is that the skin coat be flawless and void free as the gel has no "backing" if it is not. That is about it. The rest is simply a GOOD lay-up schedule and "kick" it all at once in the same day. Creates BIONIC boats. IMO...Lenny
p.s. Of the shops I have seen, they still take a bubble roller to the blown in chopper mix once they put the gun down. It is no different than a couple of "hand rolled mat" at this point. It is the rest that is important.
