I bought some pads that have microfiber cloth on the outside and foam on the inside-- palm sized. I used enough Showroom New that it didn't run, but wasn't drying out. I waited about a hour between coats. Each coat was as streaky as the last. I shook it thoroughly in the bottle and mixed it up again in a glass jar. Applied it in 70 degree weather out of the sun. Basically, I followed all of the advice I've seen. I absolutely believe it had previously been treated. I really can't blame the product. Maybe I should have wiped it down with acetone prior to applying it, but the manufacturer's instructions said soap & water (used purple power), rinsed it and let it dry. I'm not upset, Line-X is a better solution anyway.
ALSO>>> I applied some to the step on the back bumper of my 2000 Rodeo and it looks flawless.
