Paint protection

Further to my last posting, before departing on my Telegraph Track trip, I enquired on this forum about paint protection, as I was going to be driving through lots of overgrown tracks, and received a heap of good advice.
I chose a product called Auto Skin, which cost me about $55 for a litre. It appears to be similar to PVA woodworking glue. I applied it with a sponge roller and gave the sides of the wagon about 3 coats - by the time I had finished one coat, it was dry enough to start again and re-apply the next one. It eventually dried clear with a stippled finish, though in rain, it went a bit milky. It dried to a pretty tough coating, and was only moved by a hail storm in a few isolated places.
On return, a quick spray with the hose to soften the skin, and I was able to pull the skin off in large sheets, leaving the paint as new underneath, totally unscathed. From previous experience with paint damage after driving through these conditions, I was most impressed with the product, and the money spent was nothing compared with the re-work I would have had to do to the paintwork. I can certainly recommend it (no financial or other interest in the product at all)
cheers,
