Yeah, you're gonna cut a piece about 1" around bigger than you need for the hole. That much will give you plenty to mold with. Using a welding hammer and some needle nose plyers. After you have a good fit, use a pencil or popsicle stik on the outside with twisty ties. Twisting the pencil to draw the mesh tight. Use the opoxy you want and be genarous with. Cause no one is gonna see the inside. For the places that might not want to stay down use the weld stuff. It's clay like and will fit in good where the opoxy won't. Oh and make sure you use the thicker opoxy or just the weld. The other stuff will just run. I ended up using mostly the weld stuff. At first it might seem like it won't work but when that stuff dries it's bad arse. Had mine on all season and no discoloration or glue breakdown. One thing to consider is if you want to paint the mesh before putting it on. I wish I had. Just keep posting in here if you have any questions. Any at all cause that shiznit is on when it dries. Very inexpensive mod and looks bad arse.
