update
sent sample to fgci, they held on to it until i was ready.
ordered monday, received wednesday
customer service is good.
color is labeled last name, color,and mix code. ie "smith white, fciwg-123-x.
no test, had 3 different rollers set up just in case the all purpose 3/8 nap 4inch went sideways.
also cheap 97 cent 1" chip brush worked fine
after using it and seeing how it rolls / flows, i think 1/4 inch nap will yield better results.
just mixed 8 ounces at 1 1/2 percent (maybe a touch hotter) which is minimum recommended,
followed a recommended 60 second mix time,
pot life 15- 20 minutes in cool temps
dump and roll, goes on like thick paint, no problems on vertical surfaces.
self leveling agent is evident, but sanding will be required, (also allows air cure).
i did the entire interior surface of dash and fairing w/ first mix, maybe i went a little thin but was being careful and had to move fast.
coverage is good, after sanding to smooth and remove the surface agent i'm saying 3 coats will finish job
so maybe not for anyone who can mix, match and is set up to shoot gel, but for the backyard non pro like me it's good stuff.
this stuff can be shot tho, so it could be helpful depending on the job.

thanks guys,
the pics are about 15 minutes into the first coat and is still see thru in some spots (over new glass)
a few things i learned today,
1. it dried in 1 1/2 hours but first coat went on too thin ( i was afraid of runs sags and it dripping on the all the work below it) its dry and hard but has a tack
2. fgci recommends it be 14 mils or credit card thickness so it builds heat and cures faster.
3. tech said a water wipe down will remove the tack similar to wiping blush off epoxy,
i did and it made quite a difference. sunlight will cure it as well but we're cloudy all week.
i'll take the clouds and sporadic rain everyday over what those people got in texas.
4. the color match is awesome
i think the product is good, but my mistakes earned me a little more planning and work
even tho 1st coat was too thin the bonus was i could see the 9 spots that are about a square inch or so i missed and can be fixed,
and the 2nd coat will be thick enough to cover the 3m premium.
here's the dash from the start

How do you bring it back up to a bright shine after sanding? I just did paint on my Excaliber 38, but want to do Gelcoat on the top half of the boat. Looks like this would be easier on the large deck than finding a way to get high enough to paint without touching the surface. How difficult was this and how long did it take you to roll on each coat? Also, do you have to let each coat flash like you do with coats of paint before rolling on the next coat?
