Sorry if this has been covered but the search isn't working well on my phone. I have a few different shantys and they all have small pin holes where they are sewed together and from wear and tear. I've heard of people spraying the insides with this stuff. Any one have any experience with this? Looks like it would work good but I'm not sure how it would hold up after a few seasons. I have a folding shappell a single man clam flip over and an insulated otter lodge with the gray material. I'd like it to be black since I use it for spearing sometimes. I think it will stick to that material pretty well but not sure on the others. I'm gonna buy a gallon and spray all 3 of my shantys if it sounds like a good idea.
