I also put this HOW TO up: http://www.ranger-forums.com/forum2/...ad.php?t=10026
Its similar to the one you linked but with some extra info and tips that I came across while doing several emblems.
Most importantly, if you DONT want the emblem to turn YELLOWISH after a few months, then you need to use a different type of GEL. Ive read that Everlasting Elegance will not yellow out any color. Its a bit more expensive than the envirotex and I could only find it online, not in any stores.
