Throw down.

The Foam Thrower Slim is the more refined build in our foam cannon lineup. It lays down the same thick, even foam you already know, in a cleaner, higher-quality package. The clear bottle lets you see your soap level at a glance, a weighted ball on the straw follows the foam so you use every last ounce, and the solid, low-profile body sits stable while you work.

Dial in your coverage and thickness with 360° spray control, and a built-in filter keeps debris out of the line. The upgraded quick-connect fitting sets up fast and holds tight, wash after wash. Same foam you trust, in a smoother, more dialed-in cannon. It comes down to preference.

The Foam Thrower Slim is not compatible with a garden hose. It runs on a pressure washer at 1600 to 2200 PSI.

How to Use

1. Add 2 to 4 oz of your preferred Shine Supply soap, then fill the rest of the bottle with water.

2. Connect to your pressure washer and adjust the foam output and spray pattern to your liking.

3. Apply a full, even layer of foam across the vehicle.

4. Allow the foam to dwell, then proceed with your contact wash.

5. Rinse out the bottle and sprayer after use.

Detailer Tips

Soap first, then water: Add your 2 to 4 oz of soap before filling with water for the richest, most consistent foam.

Use the right soap for the job: Maintenance washes and heavy decon call for different foam.

Let it dwell: Give the foam time to break down dirt before you rinse.

Dial it in: Adjust the 360° spray and foam output depending on coverage and thickness.

Rinse it out after use: Keeps the weighted pickup, filter, and sprayer performing consistently.

Highlights

Weighted pickup ball: Follows the foam as you tilt the cannon so you use every last ounce of soap in the bottle.

Built-in debris filter: Filters the pickup so you are throwing clean foam, not grit.

Dense, shaving cream-style foam: Smooth coverage and improved consistency with reduced soap consumption.

360° spray control: Customize how thick and wide your foam lays down, at any angle.

Low-profile bottle and quick-connect: Stable base and an upgraded inner fitting for faster setup and a secure connection.

Pro-grade reliability: 1.2mm pre-installed orifice, built for detailers, by detailers, wash after wash.
