I WAS ABSOLUTELY SHOCKED (AND YOU WOULD BE TOO) ONE TIME WHEN I HAD PURCHASED SEVERAL MOBIL BRANDED OUTBOARD MOTOR OIL QUART CANS FROM AN ESTATE SALE. THESE HAD CRUSTY MASKING TAPE AND MAGIC MARKER ON THEM.
I USED LACQUER THINNER ON ONE OF THEM TO SEE WHAT WOULD HAPPEN (THE WORST LOOKING ONE) AND LIKE I SAID....I WAS SHOCKED TO SEE THAT IT CLEANED THE CANS AND DIDN'T TAKE OFF THE PAINT. I WAS LIKE "WOW!" TO THIS DAY I AM STILL WONDERING WHAT WAS USED TO PRINT THOSE CANS.
AS MANY OF US KNOW USING LACQUER THINNER ON AN OLD OIL CAN OR PAINTED METAL SIGN IS AN ABSOLUTE NIGHTMARE!
