One of my friends got a free Star (12'?) raft for free. On the bow and stern there is what she was told is called a "sunburn". It looks like rust coating the top of the tubes, but it is sticky like glue. We rubbed it down with a bunch of MEK and that seemed to take away most all of the stickiness, but the rust colored stain remains.
I was just wondering if anyone else has encountered a "sunburnt" pvc boat before? Why does this happen? It looks like it should be fine to use with the coloring, is there any reason why she shouldn't use this free boat because of the stain?
If you are lucky enough to be in the mountains, you are lucky enough.
