Interesting. I spoke to the MCS rep too some time ago and the stuff they sell now is basically POR 15. I cant exactly remember what happed but something happened when another wholesaler took over over POR 15 when MCS had the rights or something like that which upset MCS. Then another Australian company basically started up and copied the POR 15 and its pretty much the same stuff just in different packaging and this is what MCS sells now. Also some time ago I asked POR 15 or the company that makes the stuff MSC sells and they said its not designed for plastic tanks and most likey not work. Its was also that same time that they said if you want to remove it from a tank that its almost impossible. They even sold me therir 'special' stripper thats kinda ment to disolve it. Well after several weeks, it had barely softened it. A few months ago i had to fix another POR 15 disaster. The guy couldnt work out why his bike kept stalling and thought it was 'fuel related' I took the fuel taps out and the tap filters were 95% blocked with POR 15 tank liner. I said you have to be very thorough with the cleaning process and fitting of the POR 15 as its an air dry product. He said he did all that and said tank was spotles before fitting it. I could see rust and gunk like stale fuel clumps under the liner lifting it up. I dont know why he fitted it any way as there was no need. the tank had no pin holes. Anyway, the only way i could even half get this liner out was to fill tank with water and an ice cream pot full of stones, seal it all up, wrap the tank up to protect it and then place it in a cement mixer to get the stones to make the liner come loose. Probably had it in the mixer for 6 hours over a couple days. Also had to scratch around inside with a stick to try and get the silvery stuff out and blast out with water. After that it had a good soak in acid. It certainly doesnt take an hour to remove. So i would say be very careful with POR 15 or the MCS liner and ask your self if you really want go tackle the hard job of trying to remove it it fails and lifts/bubbles. Most of the other liners like Kreem and Red, White, Blue come out real easy. It would be interesting to know if the maico guy fitted it to a brand new tank or a used tank and if he leaves fuel in there or drains it after each ride.
