Hi Mate,
I applied it myself, my advice is much the same as spraying a car, the preperation stage is the most important part, rush that and you will regret it.
It would be easier to spray it on, providing you have the correct equipment. Although saying that it wasn't hard to apply it myself, I guess it all comes down to how much time you have on your hands.
I would recomend a you leave it to cure for as long as possible to ensure a good bond.
I did big post on it around january-febuaruy time on the other forum, I tried to find it but I can't? see if you have more luck as I went through all the stages, and added a few pics too.
