Best Roof Coating

I used the ProGuard product quite a few years ago on my Sunnybrook trailer and again a few years back. At first I was quite happy with it but it has rapidly deteriorated and I am now in the process of scheduling a complete tear off and replacement of the roof covering.
You can see my post from 2012, with pictures, here.
I am afraid I can no longer recommend the use of this product.

BarneyS, your experience echos my experience with liquid repairs in a can. They look great for a short time and then deteriorate/peal/wear off in a matter of a few yrs after application.

I used a different brand with similar results, looked great for two-three yrs, then it started to wear thin in spots to the point the old roof started showing through. What didn't wear thin started to peal off.

It isn't an issue with the brand of the product or how well you clean/prep the roof. It is more of the fact that with liquid applications the liquid must be thin enough to brush/roll/spray on to the roof. Those layers will never be as thick as the original surface layer the roof had from factory and will require multiple applications to build up multiple thin layers.

It just will not last as long as replacing the roof with a new membrane.

Liquid repairs are fine if you are planning to hide defects of the roof for selling to the next unsuspecting buyer , but if you are planning to keep more than a few yrs replacing the roof is the better route.

Once you start painting the roof, you will have to paint it again and again as the paint wears out.

In hindsight, I should have taken some pix of my roof as the liquid repairs deteriorated to show the forum, it is disheartening to go through the expense, hard work and time just to realize it only gives you a few good years and then you have to do it all over again.
