Never tried
this with the Fusion, but it took off Krylon and other brands of rattle can paints. I bought it at Wal-Mart, in the automotive section. This is not Purple Stuff, which does not work like it. No bets; but the Super Clean really surprised me favorably.
I used it on the original Savage plastic stocks. Using a
plastic window planter (without holes), I put a gallon of the Super Clean in and laid the stock into it overnight. Depending on the stock and the planter, you may need a second gallon to get the stock completely below the surface. It peeled the paint loose (gel consistency) so it could be stripped off with a finger (I used Nitrile gloves, although it's labeled as biodegradable, etc.). Heat was not needed. The remainder can be strained thorough nylon stocking and reused. Use it straight, undiluted.
One note of caution, it will etch (frosty finish) aluminum. It always worked for the spray paint, and even took it off a Harris Bipod. I now have a plain aluminum Harris.
Another very powerful cleaner is TSP (Trisodium Phosphate. The Eco Nazies hate this stuff). I used it to remove accumulated car wax (commercial car wash) from a white vinyl roof. Let it sit for about five minutes. It went to from yellow to white in one pass. It also removed some wax from the paint, but left the paint alone. So I put it into the wask bucket and washed the car again. It restored the original paint to just as new color and finish. The car was a 70 Charger, Plum Crazy metallic and white vinyl roof. Oh, and a 440 Magnum, worked.
