KoolSeal is silicon based if I'm not mistaking. That's a no-no on EPDM. As time (and sun) goes on, silicon will not stick.
KoolSeal makes both acrylic and silicone based products. I used the acrylic based one and it looked good for about 4 years. I friend of mine gave it to me and no longer needed it because his new MH had a FG roof. I only had enough to apply one coat. I would use it again. I think the other brands of acrylic are similar Henry's, Heng's, Bus Cote, etc. The Kool Seal silicone based coating says it it for EPDM roofs also. The silicone based ones seem to have a longer life than the acrylic or latex based ones if you look at their spec sheets. Remember they are not pure silicone.
