CLR just made a mess.

I keep trying to use materials I already have for this project. I spent 15 minutes using my drill and a wire cup brush, but while it immediately removed the paint, it didn't seem to do much to the rust.

I have 99% of a bottle of Ospho, but no good way to apply it. I guess that the best I could do would be to soak some paper towels and weave them between the pieces of metal.

I carefully stacked and slid them into a kitchen garbage bag and tightened some zip ties around them. I poured some Ospho in there and, as I feared, it started to leak out, and it actually ate the surface of the driveway.

I put everything in a pitcher in a bucket in the garage and went back to work, but most of it stayed in the bag, and it seemed to work.

I need to treat the other end, clean, prime, paint, and install.

Those H-channels are $22 each on-line only and are actually for LEXAN Thermoclear multi-wall sheet, which is $88 each, although "10 year limited warranty against yellowing and hail damage" sounds like the right product.

It looks like you are supposed to buy U-channels for the edges, but I don't see anything for corners.

I was thinking that I wouldn't cut the pieces for the front corners, just the top, and would fold the edges over, so I could use H-channels on flat surfaces.

I think that you want to mount the coroplast like drywall, with joints on studs, but I don't understand how you would screw through each sheet through the H-channel, which isn't flat.

Home Depot does suggest screws like I bought for those sheets. I bought screws with neoprene and metal washers for metal roofs.

I don't know that I will be able to work on anything today, Mom is sending me to fix the Internet of her friend whose son lives with her and is a chain smoker.
