POR-15 Boss Gloss

Clean & Protect Plastic, Rubber & Vinyl

Treat and preserve plastic, rubber, and vinyl with POR-15 Boss Gloss. After we had tried some of the big national brands, we were disappointed with the way they seemed to fade away so quickly, and in no time at all, we had to reapply the stuff. Also, it seemed to attract dust. Our chemists told us that this was partly because the big companies reduce the amount of solids in their products to save costs, and partly because they use alcohol and other solvents. We decided to make our own premium quality product, in the style and tradition of all other POR-15 Products, with more solids, and NO alcohol or solvents which can remove vital plasticizers, and lower the life expectancy from vinyl and rubber. Our special combination of premium chemicals turned into a terrific product, which we call POR-15 Boss Gloss. We were delighted to learn that, as a side effect, Boss Gloss seems to repel dust too!

Try this vinyl, rubber, and plastic protectant one time on the interior of your car, truck, or boat. You will be delighted at the results and pleased by how long it lasts.

NOTE: Not for use on cycle seats or other surfaces where a slippery surface could be hazardous

Amazing !!!

This is an amazing product, been using it for years on the vinyl roof of my 1969 Chevelle S/S, makes it look like new and lasts quite a while also.

Great so far.....except for the spray nozzles

I purchased 2-8oz bottles of the product. I am fleet manager for my company.

The directions says to use a cloth and wipe it on and off, basically. The 2 bottles came with 2 spray hand spray pumps. They leak pretty bad when using. Wondering why they included the sprayers when it does not line up with the user directions.

The tires look great. We will see just how good the product repels dust, heading to Mackinac Island this weekend to load in a live event, much dust-dirty roads. Should know better after the return trip. And yes we are authorized to drive on the island that usually only allows non motor vehicles

Love the POR product line. Have used the de greaser and metal prep and POR-15 base coat and top coat, and love it.

Great Product

Any product that they make is an answer to a problem. You get good looks as well as great protection.


Textured vinyl or rubber should be cleaned with diluted POR-15 Cleaner Degreaser before using Boss Gloss. Shake well, pour into a clean cloth and apply by hand. Spread evenly and wipe away excess. One treatment will last for months.

ATTENTION! Use only as directed. Not for use on surfaces where a slippery finish could be hazardous like leather seats, floors, vehicle controls (pedals, grips and steering wheels), beach or cycle seats, cycle tires, brake drums, etc. Do not use on or near clear plastic or plexiglass surfaces, glass (may cause smearing), fabric, woven materials, or paint. Does not contain phosphorus. Boss Gloss will help protect materials in good condition, but is not restorative in any way.
