Mold on my newer wall tent, What do I do????

i would bleach the spot as long as your not worried about color change. 1 part bleach to 9 parts water, spray it and let it sit for about 3 min tops and rinse it well. then re apply a sealant. its not gonna hurt the fabric unless you leave it on there for a reallly long time. just think how long your white t's last. i have white tees ive washed 200 times with bleach and the fabric is fine.

Are we treating and preserving a deck or a canvas wall tent??(thats the response I got from the guy at Bravo tents)

If it works - it works. It not only works on wood, it works great on canvas too and probably costs less too. It has lasted over 25 years on my tent and I've had no rot even with all the moisture we've dealt with. Thompsons is a multi-use product.
