I buy my equipment to use, I don't care about resale value. I will most likely be the last owner of almost all my gear. All my gear is nothing but tools to me. I make sure every tool I own is taken care of maintained and works as it was designed. Cosmetics is not even a consideration.
I guided a client on a Caribou hunt in AK a few years ago. We were stalking a record book caribou. We had to crawl across a exposed bolder field. My client wouldn't put his gun on the rocks while we crawled. He kept trying to hold it in the air and crawl on all fours at the same time. He was slow and the Caribou was going to get away. I told him to crawl like me and not to worry about the scratches in the stock of the rifle. He had an off the shelf rifle, so it wasn't like he paid a fortune for the stock. He told me my rifle looked like hell, and he wouldn't treat his in the same way. I told him if he hurried up, and got the Caribou, I would buy him a new rifle with out any scratches, or he could continue the way he was and go home with out a trophy of a lifetime.
We got the Caribou and he ended showing off the scratches and talking about the long difficult hunt for years. At the end of the hunt I set up a target and proved to him, my piece of junk rifle looked like hell, but was very accurate.
I don't believe in abusing my fishing gear, but I do believe my gear was made to catch fish, I don't care what it looks like. That is me, if you like to keep your gear looking like new, and don't mind making the effort to do so, than that is what you should do. I'm sure there are people that catch more fish than me, and their gear looks perfect. I know I wouldn't have any fun fishing if I had to worry about how my gear looks all the time, and fishing is supposed to be about having fun.
