I recently bought a lighthearted gear duo (perfectly light and roomy) and have a couple of questions on caring for it. It is a used tent that was seam sealed from the factory but I would like to put another coat on it due to a few peeling areas. Do I need to remove the old sealant before applying new, or simply brush over the existing? Also, it's a bit dirty and per the site you can machine wash it. Is it okay to do this and will it affect the existing sealant?
From LHG site: Silnylon tents can be put in any washing machine will a small amount of detergent and washed in clod water. Hang them out (or set them up) to dry. Do NOT put tents in the dryer.
Thanks for any advice you can offer!!
