Nap pads vs. Foam Sponge Pads
Parko recommends the use of nap pads vs. foam sponge pads because we believe nap
better serve the objective of our system; to eliminate marks, not hide them.
Consider the effects of the use of a foam sponge pad in the polishing of fresh
The foam pad serves two purposes in the polishing or glaze step: it swells the clearcoat and it
pushes excess material into swirl marks. This gives the appearance of having eliminated the swirl marks.
As the clearcoat cools (e.g. during washing) and shrinks, the swirl marks reopen and allow material
to fall out. Other drawbacks of foam sponge pads include slower movement vs. nap pads and burn
marks on rubber trim.
Attempts have been made to counter the side effects of foam sponge pads, e.g.
surface. In our opinion, only one design has had any significant impact on the drawbacks of
foam sponge pads, that being the concave design. However, it still generates more heat than a nap
pad and provides less cleaning action.
Nap pads provide better polishing action and move faster than foam pads,
recommend the use of nap pads with Parko brand products.
