Can I use Sprayhood & Tent Protector on a cotton tent?
Sprayhood & Tent Protector has been developed for waterproofing and impregnating cloth in which a large part of plastic has been processed.
Most outdoor fabric types are "woven plastic".
If you want to impregnate a tent made of cotton or canvas, you should use Canvas & Cotton Protector. This has been specially developed for waterproofing and impregnating cotton tent cloth.
