Scratch Protection Films - First Impressions

I went to the high country last weekend, and thought I might encounter the odd bush or disused track, so I got some of that ScratchPro AP60 roll-on stuff to try. Looks like wood glue, and takes a while to roll on, but seemed to set into a reasonable film. We did indeed get some scratchy stuff, and a mate with his 100 series ended up with quite a lot of scratch damage down the side. Most of it will polish out, but it's still not something you want too much of if you can help it. When I peeled the stuff off my truck yesterday, there were no scratches underneath, so I guess it worked.

A couple of problems though. This stuff doesn't like the water, so if you're crossing rivers, or driving in rain, it gets soft and starts to run. It'll set again when it dries, but seems a bit fragile to me. Another problem is the cost. A can cost me $60, and I used at least half on one application - and that was being as frugal as I could. So, one trip = $30 for the product. Finally, although most of it will peel off like in the ads, the bits and pieces around the edges take a bit of getting off. Then when you get it off, if you're not careful the bits will float somewhere else and reattach.

Bottom line - it works, but it costs a bit and it's a bit of a pain in other areas. I'll try the rest of the can, but don't know if I'll buy more. How have others found it?
