Gunze Sanyo's Mr. Mark Setter vs Softer

Hi guys, I just bought 2 bottles of decal solution of the brand Gunze Sanyo. The name of the first soltuion is Mr.Mark Setter, and the name for the second solution is Mr. Mark Softer. I am haveing trouble understanding the function of each, since all instruction are in Japanese, and the english title is not very clear on their purpose. Ummm so which one is the decal solvent, and which one is the setting solution??

Can someone also teach me which one is to be used first, and how to use them?? than you
