Hello, I am looking into getting into the seal coating business as a side job "for starters". I have read many posts about spray units, equipment and such. I have decided to build my own and use 2-275 totes so i will have a 550 gal cap. I am in northern WI, does anyone know what type of sealer would be the best to use in my location with the set-up i will be building? Also being that i will not have an agitator and just a circulation system are there sealers that work better than others. I am also concerned on clean-up and storage, do you guys wash your spray rig after every job and how long can sealer sit in the tanks? I have also read on here about a trigger wand over the ball valve, I would think the trigger want would be much easier to control. Like i said i am just in the beginning stages and want to get it right. I have owned 2 businesses before and pride myself on satisfaction and quality. I want to charge a "fair" going rate and not cut corners like many of the fly by nighters. Also with my spray unit will i need to manually "squeege" on sealer around the edges or can the whole works get sprayed with the proper equipment and customer property protection for over spray.
