While washing and waxing my Adventurer yesterday, I noticed the caulk on the vertical surface where the roof meets the front cap has begun to crack on the driver's side. The caulk is about two years old, put on by my previous mechanic, and I was told the average life expectancy of this caulk is about two years, so I guess it's due.
My question is this: is it imperative to remove the old caulk and have a completely clean surface, or since the cracking is presently minimal, can I simply put on an outside patch, filling in the crack? The old caulk is urethane, so there won't be a problem trying to put new caulk over silicone.
The side seals still appear to be holding, as well as the vertical seal on the passenger's side, but the mechanic did the entire job at the same time. I'm wondering if I'm going to need to replace the sealing all the way down the sides in short order. I am now trying to do all the work I can in an attempt to save some money and will need advice on things I have never done before.
Can anyone provide an opinion of which sealant to use? Winnebago recommends Manus-Bond Urethane sealant and I have read many good reviews on this site about Geocel Proflex RV sealant. Has anyone tried both and can give a definitive answer of which is best?
Thanks in advance for your advice.
