It's a temporary wrap that works pretty well. I'm not saying it looks good, but it does what it's supposed to. Much quicker to apply than painter's tape.
Regarding auto paint, in general...the industry has got to come up with a better clear. I realize there are EPA restrictions they must contend with, but the paints today are just too fragile. I remember my father telling me that back in the good old days, you rarely got a paint chip (of course, those paints were lead based). But, with all the advanced chemistry today, they must be able to come up with a tougher paint. Paint chips suck.
