No, you don't need their cleaner unless you want to get it.
My seams around the perimiter and front/rear seams procedure was to use Tilex to clean the seams and areas around the seams/caulk. Then reclean the caulk with mineral spirits, followed by going over the caulk with acetone which removes all residue. The old caulk and roof area must be absolutely squeaky clean for the Eternabond to adhere to and for it to hold. Any dirt or residue left on an area where Eternabond is applied will cause it to start to peel away.
As of now, going on 3 years with no problems.
You do not want to apply Eternabond to seams or joints that you might want to remove later, like the seams/joints around the vent covers. Once down, Eternabond is a bit_h to remove.
For vent covers, antenna mounts, just clean real good and apply new caulk over the old.
As for any cracks in the fiberglass roof...well, it's not really fiberglass, but a fiberglass/plastic composit. It is only about 1/16 to 1/8 inch thick, and you may see a stress crack . If you do, don't panic. Just clean area real good, and drill a very small hole at each end of the crack. Smear some Dicor into or over the crack, and put a piece of Eternabond over it. Problem solved, and it will never, ever leak.
Had several form on our 2012 Lexington from a supposedly bad batch of roof's, and FR would never take care of it.
