I would like to apply EternaBond tape across the coach roof on the front seam. Currently there is EternaBond tape there with caulking along both sides of the tape. Can I apply the new EternaBond tape over the existing tape and caulkiing or does the old tape and caulking have to come off first ? Thanks.
The old tape and caulk does not need to come off as long as it is not coming loose from the roof and that the caulk is not silicone (aka RTV) based. Also using caulk along the edges of EternaBond really isn't necessary. The concept is about like wearing suspenders and a belt.
The problem you may have covering the old sealant is appearance. It's going to look pretty ugly with all the lumps, bumps and such. EternaBond should last a very long time as much as 10 years plus. Unless it's damaged or not installed properly I would leave it along but it you want to move forward I would remove as much of the old tape and caulk as possible. I rework the front seal on my coach two years ago. Scraped a lot of former owner caulk and replaced with EternaBond. Now I have one smooth continuous seal that I should never need to worry about.
