I am curious also. I have heard people recommending getting new interior sheets, but seems such a waste to me. I just painted mine with krypton fusion. Took more coats than I would have thought, but seems to work well. If I had it to do over, I would look into non-spray options. The ABS items seem to be a little trickier. I have had some small areas that have blistered, but overall things have gone well. I have even painted the Formica on the partition walls. Time will tell on durability. Anyway, more to the point I noticed that VTS has a vinyl repair product. I was thinking that might be something that would help. I will be placing an order today, planning on enquiring about this product. I tried to kill 2 birds as I sealed with parrbond, but where I filled holes was not pretty. Oh, and I used ABS glue kind of like bondo to fill holes on the end cap and bathroom pieces. Keep us informed if you find any good products/techniques.
