Does not use in hot climate!!!
The city I live in reaches 35+ celsius in the afternoon during september. Not even peak summer (july-august). The day after spraying it all dripped like engine oil on the ground. Underbody looked like runny mascara! Just left a complete mess on the parking space! Had to cleanup both the ground and the underbody. It didnt say anything on the label for suitable ambient temperature. Absolute waste! Bought two gallons. One black and one clear. Never buying again...!

Same great product as I am used to, just in a gallon can at a significant savings over the aerosol cans. Price cannot be beat locally. Excellent protection on everything I coat with it

We treat our vehicles regularly since we live in the snow belt. It has staved off rust for our autos. Works like a charm and goes on easily and sticks around for quite a long time. Its worth the time and effort to treat the car for preventing the rust and corrosion.

Currently it is too cold to use it. We have not been above single digits and my truck will not fit in garage. I will do a follow up as soon as possible. With ease of use and quality of product.

Use the Fluid Film Pro undercoating gun to apply this stuff as an undercoating or rust preventative. See my review of that product for more on my long term test I will be reporting back on. I can say it goes on well, does not dry or create a dry shell. I can say this makes a great lubricant that fills the void between light oil and grease. I used it on my tractor 3 point hitch components and moving parts, lubing all of the pins on my attachments that live outdoors. Things slide and move easier now making things easy to put on and take off. It is easy on the hands, too. It stays like a heavy oil, which makes it likely to do well as a rust proofer as well. Time will tell if it makes a difference long term, and I will check back in with my results. If I were Fluid Film, I'd do a test vehicle and treat the passenger side (gutter side) with this product and do nothing to the other side. Show customers the difference after 5-8-10+ years online. If their product works, it would sell itself then. I would rate the product 5 stars if there were clear data about how effective it can be. For my part, I have no plans to do only half of my Silverado, and I have coated all areas I can access, so we'll see how long it takes old man winter to rust the treated areas. I will report back as time marches on with results.

Have used it to undercoat a side by side that is used in a tropical marine environment. So far it has done a good job at inhibiting the rust that eats everything down here.
