Duren 521981 Schutz Underbody Coating Gun

This was purchased in order for me to waxoil my bongo in preparation for winter. Having initially bought a 5lt can of waxoil only to discover you need the 1lt can for the gun to fit onto I purchased a 1lt can of hammerite waxoil.As recommended I warmed the can before use as it helps flow by thinning the waxoil, using the flexi pipe addition proved useless.. as the waxoil failed to disperse evenly or in any great quantity. Fortunately I was first attempting the door inners which allowed me to witness dispersal.Removing the flexi pipe and attaching the additional nozel did help redeem it, as in this mode the gun performed well and I was able to underseal the chassis quickly and with a good coat of waxoil. As recommended I had the psi at 7 bar.

Very useful gun at a good price. Simple robust construction with adjustable air flow control and easy to clean. It was able to support an extended spray tube of 2m. An alternative nozzle would be useful for thinner chemicals, but I was able to spray much thinner rust stabilising solution into a 1.4 m long closed cill cavity effectively by constricting the supplied spray nozzle end opening and feed tube end slightly. Very useful tool couldn't do job efficiently any other way.

It worked as it should. The downside is the plastic tube kinks to easy and when it does it blows off at the gun end so the option it to cut off the he expanded end. or use a jubilee clip. As the plastic tube really needs to be longer have a jubilee clip available. A longer reinforced tube would be a good option.

Have been trying to purchase a separate can to screw onto the coating gun so as to enable me to spray other fluids besides Waxoyl undercoat. Duren have been unable to help in sourcing such a container. Any suggestions?

very good gun should come with container i had to purchase more underseal so i could use the gun extra ltr of black so had to mix with the clear underseal i had just purchased

Good quality and well made for the price, easy to strip and re-assemble for cleaning, the extension tube is a nice addition.

Brilliant gun; though threading it on to the shultz tins is a bit fiddly, had to get a special connector to reduce the end of this one for my compressor but other than that, brilliant.

Not used yet but well made and I just know it will do the jobfair price
