19. What surface preparation is needed prior to application of epoxy?
All surfaces should be cleaned of any contaminates, such as oil, grease and pooled water. Light sanding is recommended. A clean cloth moistened with isopropyl alcohol or plain water may be used to clean surfaces and to remove dust. DO NOT USE ACETONE or a TACK CLOTH to clean the surface.

In all honesty...it looks like contaimination to me. If you do a search of wood strip and canoe sites, you will hear horror stories of tack clothes and acetone...on the other side...you will see sites recommend acetone to remove oils from wood such as teak. I can personally vouch that I have never had a problem with tack clothes...but....there is a body of evidence out there that tack clothes are a no-no....
