AND HAND LAYING FIBERGLASS TENDS TO LEAD TO AIR BUBBLES INBETWEEN THE LAYERS AND IN CORNERS MOST PEOPLE USE THE HAND LAYED METHOD BECAUSE ITS CHEAPER ACTULLY .....HENCE CHOP THAT IS BLOWN IN IS ROLLED WITH STEEL ROLLERS IF DONE RIGHT TO ELIMINATE THIS PROBLEM AN REQUIRES BIG MONEY EQUIPMENT............GENERAL MOTORS CO. BELIVES POLYESTER RESIN IS BETTER THATS WHY THEY USE IT TO MAKE CORVETTES FROM THE START UP TILL TODAY ONLY THING IS NOW THEY PRESS THIER PARTS WITH ASSININE AMOUNTS OF PRESSURE........................LASTLY BUT NOT LEASTLY IF IT WERENT FOR BOB BUTTS ONCE AGAIN WE WOULD NOT HAVE THE 89 IT WAS HE WHO WHILE IN POSSESION OF JAYS MOLDS PULLED A BODY AND THEN MADE MOLDS AND A FEW BODIES BEFORE WB STARTED IN ON HIM AND HIS MOLDS DISSAPEARD LOL WE ALL KNOW WHERE THE WENT NOT TO MANY PEOPLE KNOW THIS SO I THOUGHT ID SHARE IT WITH YOU BOB WAS MY MENTOR ON BATMOBILES SO I THOUGHT HE SHOULD GET CREDIT WHERE IT IS DESERVED.........PS THERE WERE 3 PEOPLE WHO HAD RIGHTS TO BUILD 89S FROM THE WB........................OTHER THAN THAT I WOULD AGREE WITH YOU JUSTIN   (HOPEFULLY I CAN GET OUTA HERE BEFORE ANY ONE STARTS THROWING ROCKS)

Sorry but Chevrolet quit using polyester resins back in 1982. All newer Corvettes are injected molded using epoxy polymer resins, starting with the new designed 1984 body style. They needed a resin to withstand the newly designed larger seamless panels, and polyester just didn’t cut it. Polyester resins cannot be used for repairs to the newer Corvettes; it just will not adhere to the substructure, SMC can be used on some of the earlier models.
As far as hand lay up goes, the mat is hand laid and rolled out using a bristle roller hardly anyone uses steel rollers any more. Using this type of roller eliminates air bubbles by perforating the mat while rolling and wetting out the mat. We use different types of mat during the lay up process to give exceptional strength with less resin used.
A chopper gun cuts fine pieces of glass from a glass rope material and mixes it with resin and sprays it on the surface. Chopper guns cause voids, air pockets, and uneven curing causing warpage. Polyester resin has the greatest amount of shrinkage and Epoxy resin as minimal shrinkage.

Both hand laid and chopper gun sprayed parts can and should be rolled out to eliminate voids/air bubbles. The main difference is that hand laid fiberglass allows better control for a uniform thickness. Chopper guns allow for parts to be laid quickly and that is why it is popular. Many, if not most, fiberglass boat builders use chopper guns. Quality parts can and are made with chopper guns.
Here one guy is spraying glass and another guy is rolling it.

| Don’t forget hand laid is far superior in strength over chopped.

| That depends on what you're hand laying. I don't think that hand laid chop mat is really any stronger than if it were sprayed. Hand laid cloth is, of course.
