Fiberglass roof maintenance

Yes, many use it. It's a great product that works as advertised.
If properly applied, it will last a long time. Just clean the area well before applying and use a roller.
You will be very satisfied.

First thank you for taking your time to read my post. Has anybody used this product ( EternaBond RSW-4-50 White Roof Seal) rather than caulk.

It is really great stuff! You won't regret using it! Sticks incredibly well!

I used it on my 39 year old class "C", it worked better than anything I had used before. Highly recommend it!

Yea. It's much better than caulk in my opinion. It lasts.....

I use it on my motorhome. Some of it is 10 years old. Still looks good and sealing well.
Make sure area where applied is clean. I use Eternabond EC-1 Etranaclean and their primer. Eternabond OPS-1 Etranaprime.

ronfisherman pretty much nailed it. You will get a lot better results with Eternabond if the area is cleaned, and one makes sure to use a roller (not hand/palm pressure) to ensure that heavy pressure is placed on every square inch of the tape so the microsealant activates properly. Eternaprime helps in this department as well.

One thing I'd add... I'd consider EternaCaulk, or a clear non-silicon caulk for the edges of the tape. This is mainly for aesthetics to keep the edges from getting dirty from road grime, but it is another pre-barrier against water intrusion.

I used it everywhere I could think to put it up on the roof, in the clearance lights, down the sides in the rear when I had to repair some water damage below our floor. (Never heard of anyone else having damage under the rear overhang!)
The tape was preventative and it seems to have worked well. After six years I am getting some wear on the edges of the tape and where there is a ridge underneath it.
Today I used some mineral spirits to remove a bit of the tape that had torn due to a rear corner accident and replace it. Mineral spirits also cleans the surface of the tape very well.
The caulk would be a good idea. Some of our tape has oozed black at the edges and is unsightly, but if the tape on the roof is doing its job keeping water out, then who cares if it is a bit ugly?

Interesting thread. Titled - "Fiberglass roof maintenance"

And then whole conversation about "EternaBond RSW-4-50 White Roof Seal", which is mainly used on rubber roofs.

Our Seneca has a fiberglass roof. I have stuck a piece of EternaBond RSW-4-50 White Roof Seal to it to see how it seals and stays on. So far, still very stuck. Going on 6 months.

I had no idea that eternabond was mainly used on rubber roofs. I thought it was used on any penetration and there are plenty on a fiberglass roof. Since Eternabond does not require much maintenance, maybe the title should be Maintenance Free Fiberglass roof. Keeping seams caulked is maintenance. A year or so ago I had a slight cabover leak that seemed to show up only with snow and ice and after recaulking it appeared to go away. I cover it in winter now though as extra insurance.
