Drying times are dependent on air and surface temperatures as well as film thickness, ventilation and relative humidity. Maximum recoating time is highly dependent upon actual surface temperatures - not simply ambient air temperatures. Surface temperatures should be monitored, especially with sun-exposed or otherwise heated surfaces. Higher surface tempertures shorten the maximum recoat window. Roughen surface or use Amerase if maximum recoat time is exceeded.

Thinner	Amercoat 65
Equipment cleaner	Thinner or Amercoat 12

Application Procedures
1.	Flush equipment with thinner or Amercoat 12.
2.	Stir resin thoroughly, add cure and mix until uniform. Do not mix more material than will be used within pot life time. Mixing ratio is 4 parts resin to 1 part cure by volume.
3.	If thinning is necessary, add up to 1 pint Amercoat 65 per gallon of Amershield .
4.	When applying by spray, adjust pressures for equipment configuration and environmental conditions to ensure proper atomization.
5.	Apply a wet coat in even, parallel passes; overlap each pass 50 percent.
6.	For colors, application of 8-mil wet film thickness (thinned) will normally provide 5-mil dry film thickness, Clear coat at 5-mils WFT will normally provide 3-mil DFT.
7.	Clean all equipment with thinner or Amercoat 12 immediately after use.
Note: Moisture sensitive - Keep cure container tightly closed. Repeated moisture exposure will cause gellation and gassing; handle bulged containers with caution, lids may eject forcibly.
