Eternabond as preventative Maintenance

Thanks to RSDATA who started this 2015 thread.
Roof preventive maintenance

The warranty period has recently passed on our rig. I am ready to apply eternabond to the roof perimeter. I had originally considered just the front and back seams but after some inspection on the sides last week, looks like it would be prudent to cover the sides. RSDATA has covered this application well in his posts.

I have a few questions for those of you that have done this;

-Preparation. Some have used mineral spirits followed up with IPA (Isopropyl alcohol), others have used acetone. Eternabond recommends eterna-clean or acetone in this instruction doc. I am just checking with you guys, did you use acetone or eterna-clean?

Sides of front cap: My rig is a darker color. I would like to run the eternabond tape down the vertical sides of the front cap...but it would look like crap due to the bright white tape. Have any of you done it on a darker trailer?

Sealant on tape edges: I have seen several posts where folks use dicor sealant around the tape edges. Lots of commentary about no need for this due to the tape sticking so well. Did you use sealant on any of the edges?

Thanks

The four-inch wide Eternabond tape applied to the roof seams of my Roo 23SS in 2005 is still in excellent condition after 13 years as verified when I was on the roof putting the winter cover on earlier this month. No peeling or anything else. This trailer has always been covered or indoor stored at least 5 months a year in the winter but that's still a lot of time in he elements.

Preparation before taping included a ruthless cleaning of all surfaces with denatured alcohol. A couple quart cans are cheap at Lowes or Home Depot.

Sample of one (1) of course. YMMV.

I used Eterna-Clean when I did my front and back seems. Worked well and easy to use.

I just applied to my 2009 23SS this fall. Applied to end seams along with around the vent, AC unit and all other roof extremities. I used their solvent cleaner before applying. I also had some denatured alcohol to insure a clean area before applying. No additional sealant was used.

Followed the instructions completely. Decided not to go to the sided even though the unit is white. Instead I'll reseal this spring with the correct caulk/sealant.

Good luck. Merry Christmas.

In my case, I went right over it. I viewed numerous videos on the way to apply. No need to remove the old sealant.

Same same. Directly over existing caulk. There were big blobs of caulk over rivets or screws (or something) that I razored flat on one end and left the other end as built. Both ends are fine and unless you're 30' above the trailer the blob raised nubs are invisible.

I cleaned with soap, water, and scrub brush, let dry one day. Then cleaned with lacquer thinner as I worked an area. 4 inch strip on back, then cut into 2 inch strips for sides, then 4 inch across front. All tape rolled down with heavy metal roller. Applied over old sealer except for couple of Big blobs which I trimmed. No additional sealer needed.

I just cleaned mine good with mineral spirits and applied right over sealant.
