Por 15 vs. Chassis Saver: Detail Analysis

Rust protection is essential for the vulnerable parts of your vehicle, such as the undercarriage and chassis. Por 15 and Chassis Saver are both beneficial coating products for rusty and damaged surfaces.

Function

Both Por 15 and Chassis Saver function similarly as a way of coating rusted and damaged car surfaces. Each of these products delivers protection from oxidization caused by water, salted roads, and other hazards.

Por 15 stands up to the test of time, lasting fifteen years or more if the surface gets prepped correctly. It is a product that coats nicely even over tough rust spots and destroyed or oxidized metal. Chassis Saver is also suitable for exterior application. Still, it won’t last as long because it doesn’t get mixed with a UV protection agent. The coating will break down and peel off if exposed for too long to UV contamination or even vigorous cleaning with a pressure washer.

How to Use

Most people who use Por 15 and Chassis Saver brush it on. If using a spray gun, you should get adequately trained. Otherwise, there is a risk for inhalation of toxins. Proper ventilation is needed for both products to reduce the risk of lightheadedness and nausea.

Both of these products are messy and hard to clean off your clothes and body if they drip on you. Some surface preparation, like sanding with fine-grit sandpaper and cleaning, is necessary for using both of them, as well.

Since the application process is very messy, you should cover your hands, face, and clothing and put down a drop cloth with both of these products.  Also, you will ruin the paintbrush you use with both products. If Por 15 gets on you, it requires paint thinner and vigorous scrubbing to remove your skin. Chassis Saver is a bit easier for cleanup with lacquer thinner.

Curing Process

Everyone wants a nice clean coat, even if it is a rust protector on less visible surfaces like these products. However, Chassis Saver cures less quickly and shows drips and brush strokes more easily due to the product’s viscosity. On the other hand, Por 15 cures rapidly but still leaves a little more time for proper curing and a smoother finish than Chassis Saver.

Preservation Method

Preserving both of these products is difficult once you open their cans. The can of Por 15 is very cheaply made and thin. You will surely destroy the can if you close it and try opening it again and again.  Additionally, the product tends to harden quickly, so the can is not suitable for preservation for any length of time. Conversely, Chassis Saver preserves a little better in the can than Por 15. However, it is a very messy product that has a limited shelf life once opened. Using something like a plastic wrap over the opening of the can under the lid helps keep moisture trapped and prolongs the usefulness of the mixture.

Finally, Pro 15 and Chassis Saver are incredibly hazardous products that should get stored in a well-ventilated room once opened. Never leave an opened can of these products unattended in a closed room for longer than necessary. Use ventilation measures in an enclosed space while brushing and use respirators if spraying these products.

Chassis Saver Rust Preventive Coating

Exterior

Por 15 has a marvelous exterior semi-gloss finish. The exterior coating of protection looks exactly as advertised and has fewer air bubbles and bristle strokes in it. On the other hand, Chassis Saver does not look the same as it gets advertised.

The Chassis Saver product is inferior to Por 15 for exterior coating because it does not hold up to UV exposure or washing. Chassis Saver will begin peeling after only a year or so if kept in direct sunlight because it lacks the UV blocking ingredient that Por 15 has.

Price

Both of these products are available at a premium price. Chassis Saver doesn’t break the bank, but it still retails for $93 per gallon. Por 15 is very expensive and costs $145 per gallon.

Outro

Between Por 15 and Chassis Saver, the more economical option is the Chassis Saver coating. However, if you go that route, you are sacrificing quality. Por 15 is superior in most categories and lasts longer, especially on surfaces in direct sunlight and contact with washing.

Overall, Chassis Saver is suitable for minor jobs that only need a little coverage. You might pay more for the Por 15 product, but it is superior in performance and function.
