Now I don't know what I used! I got some (10 ft) 4" White Eternabond they sold from an open roll. I will have to go back and find out what kind it is, WB-4 or RSW-4. Or does that make any difference to needing the UV protector?
The RSW-4 has the white smooth plastic type top layer and that is the UV protected version. It is also the one that you must be very careful and not put it under tension and is difficult to form to very uneven surfaces.
The WB-4 doesn't have the white layer and is not UV protected so it must have a UV protection top coat put on. It is less subject to the tension issues that RSW-4 has and is easier to apply over very uneven surfaces since it more pliable.
The most commonly used is the RSW-4.
BTW even the RSW-4 comes in two thickness of the microsealant, one standard that most use and one with a much thicker layer of the microsealant and that version is better for the more uneven surfaces like maybe the dimpled aluminum you used to see used on roofs.
After what I call extension experience with Eternabond the three keys to a successful install are:
1. Clean, Clean, Clean and I use lacquer thinner on a rag then wipe the surface for a final cleaning.
2. Lay the Eternabond lightly and DO NOT STRETCH or PUT UNDER TENSION and they roll it REALLY REALLY GOOD to activate the microsealant. You can see how I used it on the uneven surfaces around my ladder top in the ETERNABOND LINK in my signature and even on the four corners of my trailer roof. Here IMO the secret is OVERLAP and while the visual results are not often pretty on my trailer it has stuck like cement for almost 10 years now since I first put it on back in the spring of 2008.
3. To help in #2 above I recommend removing all or as much as possible caulking first and to make sure you have at least 1" or more good contact to the virgin surfaces for the microsealant to adhere to. I have had it stick good with as little as 1/4 to 1/2" contact at the edges like going from the roof over onto the top metal insert molding down to where the vinyl insert strip go into the molding. I also had equally BAD LUCK on something as simple as a 1" wide aluminum trim strip that is curved down slightly on each side which is used like along the bottom of trailers to cover where the siding and the lower wider aluminum trim along the bottom of the trailer is.
I'm also a BIG FAN of the double sided version of ETERNABOND for sealing things like screws, lights, etc. and again the link in my signature shows how I used it for those items.
