 They come as transparent, semi-transparent, and solid color, and I'm a big fan of solid color because the more color you put on there, the longer it lasts, the more protection the wood gets as a result. So that's basically where you're at. I would either clean it or do a stain stripper on it, depending on whether it had stain on it before, and then I would use a solid color stain, and you should be good to go for a good 8 to 10 years.
