It's probably best for some folks to use foam applicators with more of a "closed cell" formulation to apply waxes and sealants.
A lesser amount of the LSP products will be absorbed into this type of applicator...equaling less product waste, it's said.
-Tire Dressing foam pads are generally made from a more "open cell" formulation...
thus allowing more absorption of the tire dressing product
well into this open-cell foam...Thereby:
Equaling to less waste of a tire-dressing-product while performing perpendicular, circumferential-wiping-movements.
That...and along with this soft-foam being able to conform to the contour of a tire more readily...
is considered advantageous, by many people, in this arena of detailing.
However...
Let it be known that I have also used similar tire dressing foam applicators for/on:
Interior and exterior trim; "rubbers" other than tires; plastics; and vinyl.
So:
If
you believe that
you won't mind losing a little bit of an LSP through more-of-an-open-cell-pad's absorption...
Then go ahead and give these particular tire dressing foam pad applicators, that are in currently in question,
a spin around the block...and report back with your findings.
IMHO:
Not a bad trade-off for any "peace of mind" you may obtain in using these
very, very soft tire-dressing
applicator pads, with your choice of wax/sealant, on your vehicle's scratch-sensitive paint-work.
Let the sealing (and healing?) begin!!
