Recommendations for sealant tape for roof seals around vents etc

[HappyHeather]

Hello funsters
Any recommendations for waterproof sealant tape to use on van roof on top of the seals? I've heard someone on here talk about it but now can't find the post.
Thanks for any feedback

When I replaced the roof bathroom roof vent I used tape as supplied by Magnum Motorhomes. I think it’s Butyl tape but I can’t remember the make. It is on there web page under sealants.
