Rubber Roof Treatment Recommendations

I've done quite a bit of searching on this topic, and there doesn't seem to be much proof that using rubber roof treatments do much. Keeping the roof clean seems to be the best thing you can do. Storing inside will really help. The most important thing is to clean and apply sealant to seams, joints, etc to prevent leaks.

On the other hand, using any of the protectants made for rubber roofs doesn't hurt and some claim that it makes it easier to clean the roof.
