Woolwax Pro Undercoating Gun by Kellsport

Worked great with fluid film. Every thing worked great.

Sprays nice. Easy to use. Makes job so much easier. I used wool wax. Great investment.

Works well. Gave a lower star rating because two out of the 3 quart containers were damaged and I couldnt use them. Had cracks in them and air leaks out.

Works great!! Used with Fluid Film to rust proof a pickup.

A little pricey in my opinion but works great to spray warmed fluid film.

Works well. Works better if the fluid is warm. Thins it out a bit.

Works perfect!

Beware trying to use in winter cause your late getting an undercoat on. If the stuff thickens enough to clog the spray its got a surprise pressure relief that turn it into the Dilophosaurus from Jurassic Park.

Used to apply Fluid Film that was purchased more economically than through Amazon. Applied to 2 vehicles so far. Works very well. Used to preemptively prevent New Hampshire Seacoast rust on a 19 Silverado 1500 that I plan on keeping 20+ years. Hit Youtube and call Fluid Film if youre uncertain about how to do this. Fluid Films Customer Service is exceptionally helpful.

Used it to spray Fluid Film under my truck. Kit comes with everything you need and works very well. Don’t waste time or money on cheaper alternatives just buy this one it will last for many years and make the job much easier.
