My turn for a story. Years ago a friend and I decided to paint some stripes on his convertible. Top had been armor all'd many times. No matter what we tried, laquer thinner, enamel reducer, etc. masking tape just fell to the ground. Time for a woman's advice huh? He asked his wife if she had any ideas and she replied "have you tried formula 409". You could see Mel cringe embarressed that such a stupid idea be mentioned in front of one of his friends. Well long story short, after trying every other product in the garage, Formula 409 was the only thing that removed Armor all sufficiently for tape and finally paint to stick.
