Application Procedure HONEST 8838
1. Flush all equipment with recommended cleaner before use.

to avoid bare areas, pinholes or holidays.
5. Double coat all welds, rough spots, sharp edges, rivets,
bolts, etc. to ensure proper thickness.
6. Check thickness of dry coating with a non-destructive dry
film thickness gauge. Recoat if greater thickness is required.
Note: If the maximum recoating interval is exceeded,
roughening of the surface is necessary to ensure intercoat
adhesion.
7. Random pinholes, holidays and small damaged or bare areas
can be touched up by brush when the film is dry to touch.
Larger areas should be resprayed.
