i had my best luck when i kept the goo pretty thick... i still have a few stress marks in the repairs in some spots. i used donor plastic from another attex (thanks don)... not sure if the chemical composition of all ab is exactly the same, so i wanted as close as possible. i brushed acetone on and around the repair area, let it tack up for 20 minutes then brushed on the goo. i did my repairs when it was about 70 degrees outside, and on nights when the humidity was low. temp and humidity made a huge difference in how paint cured when i was painting cars so i just went with what worked best there when choosing the conditions for my abs repair. seems like it worked ok, but i haven't run the machine yet, so i can't say how it will hold up. hope this is of some help to you, and welcome to the site!
