my question is how does she know it is 100% the same; will it come out when washed. Just like there are glues made for fabic but it doesn't come out unless washed right away and can get hard and leave marks. I buy the spray at Walmarts because it does just as good as 505 but is alot cheaper. I'm not so sure about the one for cars. I'd hate to ruin anything that I made because it didn't come out.
