Hi, glad to see someone reads this group.
Ok, so having given both swags similar usage over the last few years,
albeit reduced usage due to Covid, there is as yet. very little difference.
Both swags retain the slight odour of the proofer that was used, not
overpowering, just a hint.
Condensation remains almost nonexistent in both, just as prior to
treatment, hence breathability is unimpaired
As for water repellency, The discontinued Grangers product(Mesowax) may
just have a very slight, almost insignificant edge on the Stormcare.
Under dripping water, the swag treated with the Stormcare started to
show areas where the droplets were not beading and running off, and
began to show a damp patch. I must stress however, that water did not
migrate through the canvas at any time, and I would not consider the
product inferior, and it may quite possibly be an inconsistency in
application to blame.
Bottom line, nothing to choose between them, the Stormcare canvas
proofer and preservative does as good a job as Mesowax ever did!
So will I continue to use the Stormcare proofer? Definitely!
