Used the leaf blower for years on both the bike and car. Worked great and then had an old 100% cotton flanel sheet that I get the remainder of the fluid.
Purchased a mini Hog Blaster Sidekick (smaller version of the hog blaster) from a site member November '13. Used it for the first time this past April and haven't looked back. Easy to use/carry/handle, works like a charm and little to no follow-up rubbing. Cut down my drying time and I'm VERY picky on spots....don lyke 'em. In the shade, no issues. If you are washing in the sun, you have to keep the bike damp as you wash it so you don't let the water stand and spot. Otherwise, no issues.
The HD unit takes two hands to use. Looks like the same basic design but my Sidekick is a one handed operation all day long.
Also, I've been using the HD Sunwash and have noticed limited spoting. Helps with the drying process, too.
