Here's a good one!
A county ambulance guy came in looking for "874", 4" tall, Impact in silver metallic and one in black. I used Oracal 751 for both. He just came in and said my silver vinyl is terrible. It stretched all over and bubbled and was the worst vinyl he ever worked with. He went on to brag about how he's lettered multiple ambulances in the past and his vinyl was always nice and thick with a laminate on it and this stuff I gave him was just cheap.. He bragged about how he only uses 3M and how nice and thick it is and that it has a nice laminate. Hmmm...I said you must be talking about printed vinyl because all cast in colors is 2mil and there's no separate laminate layer on it.
Being that he's so much more experienced than I am, I'm surprised he didn't know the difference between printed and cut vinyl! And never heard of Oracal? I explained it all to him.
Then he told me what really happened...it was very hot that day and the Bronco was in the sun and he used Windex and expected to be able to slide it around. It stuck immediately and as he pulled it up to re-place it, it stretched. With all his experience, it was shocking to hear. The truck with the black vinyl was in the shade and he got it in the correct spot the first try.
I should probably hire him as an installer, his skills are superior to mine by a long shot!
