In my opinion, saying a leaf blower works just as well for drying a truck as a dedicated vehicle dryer like the
Master Blaster, and costs much less, is really no different that saying an STX F150 works just as well as a Raptor, at half the cost, so who would buy a Raptor.
While both a leaf blower and the
Master Blaster Revolution move air, they perform very differently when put to the task of drying a vehicle, especially a truck with the high reach to the roof.
Unlike a blower, which is awkward to effectively direct the air stream to get into the nooks and crannies where water hides out, or to direct the water in the best direction to get it off the truck, the flexible hose on the
Master Blaster makes it simple to get into all the vents, the recesses on the windshield cowl, window trim and door handles, and off the hood and roof.
While the leaf blower will remove the bulk water, the directed stream and the easily maneuverable hose/nozzle make it possible to really direct the water off of the truck, in the best direction for each area.
And, like previously posted, the
Master Blaster uses filtered, heated air.
In addition, the rubber nozzle on the
Master Blaster is not going to scratch your paint if you accidently bump it. Bump your paint with the plastic leaf blower nozzle, then you better get out the machine polisher and correct the damage.
Yes, they are expensive, but I have yet to read a forum post from someone that bought one and then regretted it, or thought that a leaf blower was just as good.
A more economical option for a dedicated drying blower is the
Sidekick Blaster. While it does not move as much air as the
Master Blaster, or a leaf blower, it has the advantage of using filtered, heated air, and can be directed in the best manner to make the drying the most effective, to not only get the bulk of the water off, but to get into the places where the water hides out, so you don't get streaks or spots when this water eventually drips out.
Certainly, people use and will continue to use leaf blowers to dry after washing, but simply put, it is not the best tool for the job.
