... do I just clean up and remove any old seals, replace with silicone and then cover with Kool Seal Elastometric, do I need to use a primer first?
Thank you for any help.
Not trying to be disrespectful, but the above is 100% wrong. DO NOT use silicone. Silicone will stop holding after a few months in the sun on a rubber roof. Use Dicor self leveling caulk.
DO NOT use Kool Seal. Kool Seal will dissolve when there is a standing puddle on the roof. These are the normal spots that leak on an RV. The place you need protection the most will be compromised by using Kool Seal.
Instead use a product like this one that can handle puddling:
Plas-T-Cote
If I had to guess I think you have a leak around your rear ladder connection to the roof and/or the rear cap to rubber roof point. These are common weak point on older rigs.
