Roof leaks

Can someone recommend a good sealant/chalk for repairing a leak on my 95 B190 motor home?

I like Silkaflex 221. It is a bit less sticky and easier to apply than what Airstream recommends but have noticed the white tends to yellow......

3M5200 works well. Do it right the first time as it is nearly impossible to get it off.

Ummmm, not me. 3M 5200 is more of an adhesive than sealant and you are right, it is permanent. I'm not sure I would use it even if I were building a new trailer and overlapping aluminum panels. There are quite a few threads on the forum about sealants and where to use them. I am a proponent of 3M tape on the roof seams.
