Ipe deck needs to be restored
My contractor installed our ipe deck in February and it's time for us to get it back to the original color. I've read some of the postings about the RAD system and TWP. Do I have to buy these products through the manufacturer's websites or will I be able to find it at a local retailer. I'm in northern NJ. Also, I read one post about TWP #116 and another about TWP #516. What is the difference and which one should I use? I've also read a few posts with some spotty finishes that look like water spots. What's the best way to avoid spots?
