What can anyone tell me about using pvc...pros and cons...an artist friend is painting large mushrooms to be cut out and attached on a farm silo...someone has suggested to her thin pvc...she has asked me for info...my days of sign making were concentrated in dimensional stuff so I used wood and HDU only...the silo of course has a slight curve so a little flex would be good...seems like I remember seeing what I thought was a thin 4x8 pvc sign crack up really bad...anyway told her I knew where to go to get the answer...so here I am...maybe you guys could suggest what would work best for her.

The PVC might work,,but,,,,,in the heat of the sun it might worope, worpe, wopre,,,you know big all weird and out of shape. Maybe 1/4 thick might hold up better.

Alicia...your spelling attempts are the best laugh I've had today...all of us can identify with the problem you had trying to spell "warp"...on any given day any of us can come up with some the craziest ways to spell a word...maybe a word that on another day we would have no problem with...you should see some of mine...but your attempts are the best.

Rusty, PVC does have a tendency to warp and the thinner it is the more it will warp. You'd be better off with an aluminum composite like Dibond or just straight up aluminum.

the diabond or max metal would be the best. its a PVC with a thin aluminum less then .024, maybee .022 on both side of the PVC. best of both worlds....bendable and the aluminum will keep it from wooooooooooooooooooooooooorping warp warp warp.........speed 7

Unless it is a very large diameter DiBond(or any of the others) will be hard to bend to fit. I would use .040 aluminum, and fasten with 3/16 " Large head pop rivets.
The drawback to aluminum is that it is hard to cut clean with a jig saw, and very slow with snips. If the mushrooms will be the same size and shape I would cut a pattern out of MDF and use a pattern bit in a router to cut the aluminum. Actually I would probably do this if they are all different, because MDF is cheap, and the cut is so much smoother.

I made up some yard deer using 1/4 pvc to test for the winter.
They made it through the weather just fine.. Also made a nativity scene using 1/2 pvc. It was plenty tough. Made it through the winter as well.

I'm with Joe on this. The large radius of a silo should not be a problem at all for 3mm Dibond.
