I will take some pics of the back side of the grill today and post them.
I got the 16"X48" size so I knew I would have plenty of material.
I did use zip ties and I know they will get brittle over time. I have found two plastic products that will allow you to adhere plastic together for two different applications.
The first product, Plasti-Mend Black 4oz, https://plasti-mend.com/cart/index.p...&product_id=79
The picture of the product is just a stock pic. and makes it look like there are three cans but you have to pay attention to the quantity on the description.
I have used this product and it works great for bonding plastic or filling plastic cracks or holes. It's fairly thin/liquid that starts to set up or skin over very quickly due to quick evaporation of solvents. I will be using this to adhere tabs that I am going to make so I can get rid of the zip ties.
The second product, PlastiFix, http://www.urethanesupply.com/PlastiFix/
can be used to secure the mesh to grill permanently without worrying about getting brittle and cracking. After you bring up the web site, look on the left side of the web site for the Information and Instructions blue section, find and click on the "Videos" at the bottom. Next, go to the second page of the videos and click on the first video at the top. It shows the best way to make tabs and use the plastic powder to bond plastic material together, like grill mesh to a grill. I haven't used this product yet, I will be buying it next month.
