Best new packaging yet

We have been undercoating 3 vehicles twice a year, first with Fluid Film and now Woolwax. Always a pain to get the gallon cans and struggle to open them and then pour into the sprayer. The addition of the plastic pour tops was an improvement but this new packaging is the best yet. And no rust on any of our vehicles, even with the brine solution used here. Great package, great product.

Rust Bucket Owner

Using the Woolwax Undercoating, Black, on a previously-rusting truck, I'm pleased with it so far. I took an electric wire brush to the real flakey stuff, then washed and air-dried the majority of the frame. I applied with a cup and paint brush, and was not hesitant to apply heavily in areas where I needed it to creep inbetween layers. The smell isn't bad - A little like a clean farm - And it was easy enough to work around on a hot day in close quarters. Ambient temp was 90F, and you could see an 'oily' creep begin as the Woolwax 'soaked' into the dry and crusty frame. The black color was appreciated, as the undercarriage looks slick and black now, instead of baked and rusty. It DOES stay wet, but I haven't seen any product transfer (splatter, wind-blown). After 100s of miles, it still has brush strokes in it. It will easily get on YOU however, similar to working on a truck with a bad oil leak. This truck lives in the south, but travels north and into corrosive-dirt environments. I look forward to putting the Woolwax to the test in these environments, and see if it can preserve what's left of this frame.

Great Product

I've been using this product on my truck for two winters, going into the third. The underneath still looks great. I touch up the spots where it may be exposed more. But so far, no rust or flaking from the frame.

Fast easy rust protection

I have had WoolWax applied twice and this was my first time applying it myself. I couldn’t have been more pleased with how easy and fast it was to apply. I’ll be touching it up myself again next year and expect it will add years to the life of my 200 series Land Cruiser.

Great product for inner panels and the undercarriage of vehicles. I’ve used Fluid Film in the past and it didn’t last a few rain storms in the summer months so I needed something that would last longer and get though the harsh winters here. We get around 170-240 inches of snow annually. Woolwax is also more stable than Fluid Film as Fluid Film in Black separates after it’s applied and doesn’t look so good. The black runs leaving a very uneven applied look. I didn’t like the strong smell of Fluid Film, Woolwax Has virtually no smell. Overall great product that outlasts the rest.

Undercoated new truck 2 weeks ago , so far very happy with the application and very low odor ,not as messy as expected, easy clean up. As this will be my last truck I'm confident now it should be rust free for me and future buyer. I've seen fluid film was off in a couple months so I'm hoping this doesn't. I'm going to do my other vehicle soon .Thank you

Used on my 2005 F150 to protect the rusted steel. Very impressed thus far. Goes on fairly easy once you learn the gun tips, wands etc. Less smelly than fluid film. Wished I had known about WW sooner!

Excellent product, thick enough it dosent wash off. Like the black, easy to see where you miss spraying. Have used other products from different companies, this is the best imo. ??

Great product. Been using this stuff for 4 years now and never let me down. Tried various other undercoating products and nothing compares. Wool wax goes on thick and covers well. Once it has cured, it stays put - Even with the wave of a pressure washer! Also can be removed by simply wiping with a rag. Highly recommend this product!

Sprayed 2 vehicles

Applied to both used vehicles I bought this year. Also purchased the spray kit. The product goes on nicely. Hope to keep tabs on how long it stays on since the black is more visible. Have had major rust damage on unprotected trucks in the past. Will see how it performs this winter in snowy salty Vermont.
