I asked on the other thread, but how messy is co-flex if you accidentally apply to much glue and it dries the co-flex to the sheeting? Is it an easily sand-able material?
If I recall correctly, in the old thread someone had suggested to wet the sheet first, put it in place and let it dry. Once dried, the sheet would already be in the desired shape, making gluing much easier. The first time I try this technic I think I'll do this to get the hang of it.
