Those on there forum say Fusion8 and Solu-Boost is a good combination and get good results.
If you use the Solu-boost you only mix enough to do the immediate job apparantly, say a couple rooms.
I used Fusion8 today on a job. Client went out and left me to it but saying the stairs and lounge were her hates because they were grubby.
She just rang me to say the whole job, inc bedrooms, is brilliant.
