woolwax Auto/Truck Lanolin Undercoating 1 Gallon Pail. Straw (Clear) Color. Review:


Since I've started using Fluid Film, I've been dissatisfied with how rapidly it washes off exposed frame rails. Luckily, I have two weeks before I have to drive in the rain, and two car washes get rid of the majority of the fluid film.WoolWax, in my experience, lasts MUCH longer than FF. Since I installed it on my truck a month ago, I've drove through six car washes, rain, and snow, and the WoolWax is still there and still working. Going ahead, I'll buy WoolWax instead of Fluid Film because it's such a superior product.



Rust-Oleum 248656 Automotive Professional Rubberized Undercoating, 15 Oz, Can, Aerosolized Mist, Black Review:


My 2010 GMC Sierra's wheel wells had some chipped paint and overspray that looked sloppy and gave the body the impression that it wasn't protected, so I used this spray to undercoat them. I made every effort to thoroughly clean everything inside before attempting to remove the paint. The spray dried quickly and looks to adhere quite well. However, it runs out rapidly; covering both wheel wells required almost two cans. Overall, I'm pretty pleased with the appearance, but more importantly, I hope it resists rust over time. I suppose we will see. If it doesn't, I'll change my rating, but as of right now, I'm satisfied with the product as a whole.



CarPro PERL Coat Plastic & Rubber Protectant 1 Liter Review:


I thought this product would dry more effectively than it did. In my experience, the substance remains tacky enough on perfectly cleaned and degreased tires that dust practically paints itself on. I live at the end of a dirt road, so I'm used to this and don't dress my tires very frequently, so it was sort of a letdown. That might not be such a bad thing if your vehicle never left the comfort of pavement. In comparison to this substance, other treatments like Chemical Guys



3M 08881 6 Pack 16 oz. UnderCoating, Black Review:


If 3M had been able to offer me some incentives for utilizing this product, I would have given it a 5-star rating.I've had my vehicle undercoated for half a year now. So far, no problems! I remember doing some comparison shopping before settling on this particular product for the following reasons:1. Affordable cost2. The angle or direction of the spraying nose3. Environmentally friendly in comparison (maybe)At the end of the project, I did not run into any significant mess. Within a few hours, it was dry to the touch. The next day, I got behind the wheel of my automobile. We'll check its resilience after this winter's 2019 northeastern weather. I'll keep you informed. Oh, and if you are unable to jack up your vehicle's undercarriage to a height of at least 18 inches, just hire a pro. If not, you will find yourself at a chiropractor's and a doctor's office.



3M 08881 Undercoating - 16 oz. Review:


Excellent stuff, as expected from 3M.On my 2007 4Runner's rear fender wells, I applied this. The original black undercoating was flaking off, and some of the white sealer was visible (looked terrible). All I had to do was thoroughly clean the fender wells with water, scrub them with a rough brush, let them dry, tape off the sections I wanted to cover, and then apply.The product sprays nicely out of the can and has decent coverage. It dry to the touch in less than an hour without dripping or running. I only used the product once, and it was thick enough for my needs.The only drawback I can identify is that, like with any aerosol product, it becomes more difficult to spray at an angle or upside down once the can is roughly 1/4 full.



CRC 18412 Zinc-It Instant Cold Gallonvanize Zinc Rich Gallonvanize Coating, 13 Ounce, Gray Viscous Liquid Review:


It works, but only if you utilize it properly.You must quickly wipe the metal down with alcohol after clearing it of all rust, and as soon as that has dried, apply the zinc paint.Apply an additional coat or two as soon as it has dried because it dries quite quickly. After you're done, let the paint cure and bond by placing the metal in a dry location for a day or two. You might see certain spots where tiny bubbles of metal are visible. Don't stress over that.In order to remove any contamination after 48 hours, clean the item softly once again with pure alcohol with a soft cloth. Next, spray the zinc with an enamel epoxy paint that can be used on zinc. To discover a label that states it works with zinc coatings, you must visit a hardware store and read a few.Remember that this zinc paint is fairly soft and functions more or less like a primer. It constantly sacrifices itself to prevent the metal from rusting, but you cannot spray over it right away since it is too powdery for the first day or two. It is also being eaten away by the moisture in the air that is trying to rust the metal. Once the paint has been applied, air and moisture can no longer reach it, preventing the metal from rusting even if it sustains a minor scratch.



Penray 4424 Rubberized Undercoat - 16-Ounce Aerosol Can Review:


The best undercoating I've used by far is Penray. I switched to this product since I didn't like the texture of the 3m I was using before. I top coated over POR 15, and the matte black finish and beautiful, even coverage resulted. As with any painting project, preparation comes first. This product will result in an amazing finish if you take the time to do it properly.



Chemical Guys TVDSPRAY101 Protective Coating for Rubber, Plastic and Vinyl, 14.5 Fluid_Ounces Review:


I've tried them all, and this is among the greatest tire shine products available. I also employ the "Black on Black" Spray Shine variant. I cannot tell any difference between them; they are truly the same. It initially sprays out as a very thin mist that resembles water, but it will keep your tires gleaming and black for days (definitely not weeks though). It does leave a small amount of residue on your driveway, so I advise spraying it somewhere else or making sure you immediately spray your road with water to wipe it off. Otherwise, it will leave black oil stains on your pavement.Additionally, Amazon does provide this product at the lowest price I have ever seen. If you use a detailer or distributor, the cost is typically doubled.
