163 jars on this shelf, which is the half the archetype never mentions.

What it is

A wax or polymer paste, sometimes a liquid, applied by hand or machine to a gelcoat hull. Thick, taken out with a cloth or an applicator, and used a little at a time over a long session.

Which is a jar craft

A hand and a cloth go in. A narrow neck is useless, and 163 of the 354 containers here are jars, led by 101 PET single wall jars and 27 PP single wall jars.

The archetype says narrow mouth and sprayed

For a paste that is simply wrong, and the shelf arrived with the jars anyway. Worth stating because a reader arriving for wax sees a group described as a cleaning spray.

PP where it may be filled warm

71 PP containers and 16 PP round tubs. A wax poured warm needs a material that will not deform, and polypropylene is the usual answer.

Straight sided so the product releases

A set paste in a jar with an inward shoulder is trapped. Straight sides let the last third be reached, which for an expensive wax is a real part of the value.

A wide lid for working hands

26 dome lids and 10 round tubs. On a dock in the wind, a lid that comes off in one movement and goes back on without a thread is worth more than a better seal.

Although the seal matters for storage

Wax dries out and a half-used jar left for a season skins over. The trade-off is a lid that is quick in use and tight for the winter, which usually means a liner.

Black and white containers dominate

136 white and 39 black, against 54 clear. For a wax the opaque container is conventional and hides the skin on the surface, which is either a feature or a complaint depending on who is holding it.

The double wall jars are a retail decision

16 double wall round base jars. They read as premium on a chandlery shelf and waste volume, and for a product sold on presentation that is a fair exchange.

And nothing here is breakable

Which for a product used while kneeling on a hull is the right call. No glass on this shelf at all, and this is the leaf where that matters most.

The archetype behind this shelf is home-spray: 350 to 1,000 mL, narrow mouth, trigger sprayer, PET and HDPE, cold fill, thin, aqueous, sprayed. Its stated reason is "cleaning spray. Trigger sprayer, lockable, chemical resistant." All three leaves sit on it, and the shelf carries two trigger sprayers out of 526 closures.
