Best way to remove old sealant on roof around fans and vents

[Kommander]

Hi,

I haven't read every post but in my case, removing 40+ years of all kinds of caulk including silicone, I used 3M Caulk Remover to get the last bits of silicone off my fibreglass.

1974 Trillium 1300.

You may have to remove some caulk, but on newer units I've just left the caulk in place and covered the caulk seam with 4" of Eternabond tape. Do it once and forget about it.

I just replaced a fan using a Multi-tool with a scraper blade. Literally took 10 minutes. It worked so well I didn’t need to use any solvents. If you don’t have one borrow or buy one, it’s a great tool to own!

If there is actually caulk, leaving it there is not the way to go. The vents and windows on fiberglass trailers should be sealed with butyl tape, then something like Dicor or Eternabond over the top. No caulk.

The scraper blade removes all the caulk, none left. When I installed new fan used tape followed by Dicor.

Just send me a pm if you want to do it that way. Anyone who want some scrapers is welcome to contact me. But not shipping outside of the USA at the moment. Just offering this to fellow FGRV owners who are stuck, oh excuse me, safe-at-home this spring without a lot of resources. I am not trying to start a business producing them in mass.

I buy most of my supplies at the Marine stores in Seattle. The nearest RV store is a 25 minute drive, the marine stores are just a few minutes away. Until a week ago a West Marine store was just a few steps away. I will miss the convenience of that but they are still in the neighborhood about 1 mile away.

Unfortunately West Maine closed all of their stores here. I think they pulled out of Canada entirely. Either way they closed up shop in my town. We do have other good marine supply places here seeing as I live on an island and surrounded by water but at the moment I am only able to call in and place orders then pick them up. No retail shopping in store.

See his video on replacing and resealing RV roof vents.
You will be buying this tool soon. Unless you own one.
He has videos that every RVer needs to see.
You might never need a RV repairman again.

He is using a Dremel MultiMax with a stiff scraper blade.

I have a MultiMax, But I would not consider it to be worth the $$ for a one time use just to remove old caulking when replacing a roof vent. But if you want to use one then I suggest you look on craigslist instead of buying a brand new one because people don't typically put a lot of wear and tear on this tool so they are likely to be in good condition. They do often end up being sold on places such as craigslist, facebook market place, etc as they just don't get used that often.

There quite a few brands of these. The keywords for your search are "multi tool"
