The Pressol ProSeries is a double action sprayer developed with Obsessed Garage for detailing chemicals. Every pull of the trigger fires twice, so you get a continuous fan instead of a pulse, and 1.4 ml goes out per full stroke. The bottle is fluorinated, the seals are FKM, the suction hose draws from any angle and the nozzle is solid stainless steel machined in Germany. Available in 500ml and 750ml.
A normal trigger sprayer pumps on the squeeze and does nothing on the release. You get a pulse, a gap, a pulse. On a panel that means uneven coverage and a lot of pulls.
A double action sprayer pumps in both directions. One squeeze fires two sprays, so the output is continuous while the trigger is moving. Fewer pulls for the same coverage, and the fan stays even across the panel instead of stuttering.
The second thing it buys you is control. A full pull puts out 1.4 ml. A part pull puts out less. Once you have the feel of it you can lay down a light mist for a quick detailer or a heavy wet coat for an APC, out of the same bottle, without changing the nozzle.
Shorter and lighter
Fewer refills
Both use the same spray head, the same stainless nozzle and the same 190 mm suction hose, so the spray pattern and the output per pull are identical. The only difference is how much it holds and how tall it stands.
Four things, and all of them are the reason cheap bottles fail.
Spray bottles are the cheapest thing in a detailing kit and the thing that fails most. If you are replacing them every few months, the arithmetic goes the other way quickly.
The suction hose is flexible and weighted, so the pickup follows the liquid instead of pointing at a fixed spot. You can hold the bottle anywhere between upright and fully inverted and it keeps drawing. The spray head is also freely positionable, so you can aim it independently of how you are holding the bottle.
That matters more than it sounds. Door shuts, under sills, inside wheel arches, the underside of a bonnet, roof lining. Those are the spots where a conventional bottle starts spitting air.
Pressol tested the ProSeries against a published resistance table. It handles the great majority of detailing chemistry, including brake cleaners, glass cleaners, degreasers and APCs.
Cosmetic staining. High pH products can discolour the bottle over time. P&S Brake Buster, Shine Supply Wise Guy and Angelwax Vision are the ones we see most. This is cosmetic only. The bottle, seals and nozzle are unaffected and the sprayer keeps working.
Bilt Hamber Trace-Less. Do not use this bottle with Trace-Less. A separate Trace-Less compatible version of the sprayer is coming and will be listed here when it lands. Register your interest and we will tell you when it arrives.

| Set the pattern first | Turn the knurled stainless nozzle to go from a 50 degree fan to a full jet. Fan for panels, jet for reaching into shuts and arches.Set it before you start, not mid panel. |
| Prime it | A few pulls on a fresh fill clears the air out of the hose and the pump. |
| Use part pulls | Full pull for a wet coat, half pull for a light mist. Same bottle, two application rates. |
| Label it | One chemical per bottle. Cross contamination ruins both the chemical and your result.The ProSeries label sets are made for these bottles. |
| Flush aggressive chemistry | Rinse the head with warm water after a strong degreaser or brake cleaner. Pull the trigger until clean water comes through. |
| Do not store it loaded | If a bottle is going in the cupboard for months, empty it and flush it first. |
| Keep it in range | Rated for use between 5 and 30 degrees C. A bottle left in a hot car all summer is outside what it was designed for. |
Trace-Less version coming soon. A separate version of this sprayer, built to handle Bilt Hamber Trace-Less, is on the way. It will be listed as its own product. Use the bottle on this page for everything else, and get in touch if you want to be told the day the Trace-Less version lands.
Technical specifications are taken from the Pressol data sheet for the Industrial Sprayer 2024.0 in 500 ml and 750 ml, item numbers 06212 523 and 06213 523, together with Obsessed Garage published ProSeries information. Chemical compatibility guidance is general. Always check the Pressol resistance table and the chemical manufacturer's own advice before decanting, and test with a small quantity first. Discolouration from high pH products is cosmetic and is not covered as a fault.

"Honestly, these OG Pressol Pro bottles are a total game-changer. They’re built incredibly well, you can tell they actually put some real thought into the design. Most chemical bottles eventually leak or the tips get clogged up, but these feel like they're made to go the distance. The stainless steel tip is a first for me on a detailing bottle, and that dual-action sprayer is just awesome. Definitely worth the upgrade!"
"I have should have bought these ages ago absolutely great trigger and seem to use less product great coverage great nozzles and cover all angles will buy 2 more"
