Butyl tape provides the initial bedding surface for mounting items that require screws. It is the final sealant (this is where polyurethane really shines!) that is the water barrier.

I have probably replaced several hundred roof and sidewall mounted components in the last 15 years, and the only ones that leaked were those with improperly applied butyl tape or surface sealants.

And a quick word about Dicor, it applies nicely and self-levels, but will dry and crack with age and IMPO, is NOT a reliable sealant for RV use.

For many uses I have relied on 3M VHB tapes, they come in many different types and are fast becoming the choice in the automotive world. I currently use the tape on all joints and seams before I rivet. The stuff works amazingly well for sealing and bonding items together. Butyl tape for me is a product of the past and should no longer be used. Polyurethane are great products for areas the tapes cant be used or as a second line of defense, like example on the inside of the exterior skin where its not exposed to UV light or direct weather.

I don't use any type of self-leveling sealants unless I have a week to allow them to properly cure, and that includes SikaFlex 715.

I rely on SikaFlex 221 for most applications, but you have to mechanically smooth it for use as an edging sealant by plastic putty knife or the good old fashioned finger with a nitrile glove on it.

My comments on VHB tape: absolutely AWESOME stuff, but not if you ever want to remove what you have just installed!!!! I use it for the initial bonding of the feet that hold my solar panels, which are then covered in SikaFlex 221.

Sure would be nice if this info, or a synopsis thereof, got added to the most excellent sealant thread.
