wow I'm surprised everyone cares what it looks like. personally, I give you a thumbs up for putting function first. it's not as ugly as my bumper. I herculined my interior and my rims, I love the stuff.
That stuffs so much fun to work with isn't it? only reason it looks bad is the texture, looks like you used a brush? I found that the textured rollers make a much nicer texture than a brush. fortunately, the stuff bonds to itself, so another coat with a roller should help quite a bit. also, use a paint mixer, the kind you put on a drill, and mix the heck out of it. I got two of the herc kits, that come with rollers, but it says that you can buy the same rollers, I think it's a 3M product. they look like sponges but plastic, mine were blue.
