 The same product we're talking about, the siding, the wet and forget, will work on shingles. Okay. And again, you get the hose end, spray it, it'll kill it. It's going to take, you know, six, seven weeks before it disappears. You're going to think I was lying to you. But it will be gone. All right. And then re-spray it every year. You're just not going to have that problem again. It works great. Sounds good. Wet and forget, I'll make sure I pick some up. Very good, Bill. Thank you.
