Great product!
We bought this to refinish/stop the rust on our 16ft livestock/cattle trailer. We wire wheeled, sanded and then did a coat of rust converter as base. We also added rust oleum paint on outside and decided to rubber/undercoat bottom of trailer where the gravel hits as well. We used the product undiluted with the recommended gun (do not use the multidirection attachment!) with portable air compressor at 110psi pressure and disposable suit and face mask as suggested in other reviews. We have just finish applying but are pretty happy with the results so far. We used almost 2 gallons to do frame/supports, 1/3 of outside and 3/4 of inside. I followed my husband with roller against tape line to avoid overspray on top of outside of trailer and the product was already drying on a 70deg day. So it seems that the other reviews for extended dry time was due to thinning the product... that is not at all necessary and went on smoothly right out of container!The product came shipped with the containers sealed well and cushioned in box to avoid spills and punctures. It is a sticky mess to have on your hands but cleans up well with gas or paint thinner if you accidentally get a little on yourself. All in all we are happy with our wknd project (took a few weeks) and hopeful with the durability of the product. We will certainly buy again for future products!

5.0 out of 5 stars Great stuff, stays soft and disolves well w mineral spirts to thin some for spraying inside frame rails and deep inside places.
Reviewed in the United States on October 1, 2017
Don't get just one gallon for your car, I put over 2gallons onto a Ford Focus and came out great. Be sure to get 2 or 3gallons for a NEW car with 4 doors. I thinned it down some (mineral spirits) and used my own homemade hose-spray head.

Made my spray tube using some 3/8"ID vinyl tube that I heated end and melted it flat-closed. Then heated a small nail to poke/melt holes into the flattened end at different angles (Pattern like a "5" on a dice" on both sides with some poked into the flattened ends too. it made fine mists and directional into the corners of frame.

Be sure to buy some Tyvek jump suits with head coverings; cheap latex gloves, plastic sheeting to cover over & under the car. Also tape up the seams from hood & fenders so spray does not get onto finish. Pull inner fender liners and bumpers to do it right and get car up as high as possible. I used a gun that was "bought with" this stuff and worked well with mods. However the 3M spray tube (bought with) was worthless as it was way too stiff, kept kinking and causing air to blow material out gun breather hole all over me/car. Lastly use full face shield with tear off liner/shield so you can see when overspray gets on you.
