  • Cleaning Due to its matte finish, it’s recommended to use a mild soap and water mixture for regular cleaning. Avoid using abrasive brushes or harsh chemicals as they can damage the finish.
  • Lubrication The hinges and seals can be lubricated semi-annually with a silicone spray to ensure smooth folding and sealing.
  • Inspection Periodically, inspect the rubber seals for wear or damage. Replacements can be ordered if needed.

  • Cleaning The Fiberglass Reinforced Polymer (FRP) coating is durable, it needs minimum maintenance. Using a soft cloth or sponge with mild detergent and water will keep it looking new. Rinse with water after cleaning.
  • Lubrication Similar to the MX4, it’s good practice to lubricate the hinges and seals a couple of times a year. This prolongs the life of the mechanisms and ensures a tight seal.
  • Inspection Regularly check the cover for any scratches or dents. Given its resistance to dents and UV damage, it’s less likely to show wear, but it’s still a good idea to be vigilant.

In essence, both tonneau covers are designed for durability, F1 is more durable because of its Fiberglass coat. But regular cleaning and periodic inspections will ensure they stay in optimal condition for years to come.

Security Comparison

When it comes to security, both the BAKFlip MX4 and BAKFlip F1 offer similar features, that are designed to protect your truck bed’s contents.

Both covers provide notable security. Recessed cable pulls are used to release the panels, but they are only accessible when the tailgate is down. Hardcovers, in general, are made of durable materials that aren’t easily broken or penetrated.

BAKFlip MX4 and F1 both utilize the truck’s tailgate as a primary security measure. When the tailgate is locked, both covers deter unauthorized access.

However, the BAKFlip F1’s emphasis on its hardcover construction suggests a focus on physical resistance against break-ins. While the BAKFlip MX4 also offers resistance, its features emphasize concealment as a security measure.

While both covers offer strong security features, the BAKFlip F1 might have a slight edge in terms of physical resistance due to its tough material construction.

But, remember, the true measure of security will also depend on other factors like where you park your truck and for how long. Few common security measures will save you from theft.

  • Park your truck in safe well-lit-up places.
  • Always check the seals before locking the cover.
  • Make sure the Tailgate is locked.
  • Do not leave your precious items in the truck bed if you are going to park your truck for hours, especially in strange places.

Performance Comparison

Both the BAKFlip F1 and the MX4 are popular tonneau covers from BAK Industries, designed for truck beds. Let’s break down their performance in specific weather conditions.

Rain and Storm (Water Leakage)

The BAKFlip F1 and MX4 are both designed to protect your truck bed from water. They each have tight EPDM seals to keep the rain out.

Both covers have a special drainage system, that directs rainwater away towards the drain tubes which you install in the truck.

Still, in big storms, there might be a few small leaks if the cover is not set up just right. For both covers, fitting them correctly and regular checks can help keep your truck bed dry.

You still may experience some water inside the truck in heavy storms. I never saw any moisture, but I heard some folks saying, that If you want to keep something inside and want it to remain dry, try putting it in the center of the truck.

Sand and Dust Storm

The BAKFlip MX4’s aluminum build offers similar protection, while the BAKFlip F1’s fiberglass top resists sand and dust. But let’s be real here, with intense sandstorms some sand might sneak through seals.

Hail, Sleet, and Snow

The BAKFlip F1’s cool fiberglass top is pretty good at handling hail and sleet. It can take a bit of a snow pile-up, but you’ll want to clear off the big snow piles for it to last longer.

The BAKFlip MX4? It’s made of tough aluminum, so it’s cool with hail and sleet too. Although both covers can carry 400 lbs evenly distributed weight. It’s a good idea to brush off the snow pile once in a while to keep it in good shape.

UV Rays and Corrosion

The BAKFlip F1’s surface is totally UV resistant, which means it shouldn’t fade or wear out quickly when exposed to the sun’s rays. The cover also offers resistance to corrosion, given its design and materials.

The aluminum used in the BAKFlip MX4 is naturally resistant to rust and corrosion. Additionally, its premium UV-resistant finish ensures the cover remains in good shape even after prolonged exposure to sunlight.

Both the BAKFlip F1 and MX4 offer solid protection against various weather conditions and elements. If you live in an area with frequent extreme weather conditions, you might want to consider BAKFlip F1. It is robust, strong and offers premium quality.

Which One is Value to Money? BAKFlip F1 or MX4?

First off, looking at the price, there’s a bit of overlap. The MX4 stays within a tight price range of $1,199 – $1,249, while the F1 has a broader spread of $1,049 – $1,299.

If budget’s on your mind, you might snag the F1 for a little over a grand, but on the higher end, it can go up to $1,299.

Feature-wise, both of them are kinda showing off. The BAKFlip MX4 with its aluminum build is all about durability and resisting the elements, especially rust. The BAKFlip F1, on the other hand, is flexing its fiberglass finish to ward off sand and dust and it keeps it cool under the sun.

If you’re after an aluminum core and finish and jet-black appearance, the BAKFlip MX4 is for you. But if you’re looking for durability and a scratch-less appearance because of that fiberglass strength, the F1 might be your catch.

Both offer a 5-year warranty. You must go through the warranty guidelines at the time of purchase.

Wrap Up

In a nutshell, both the BAKFlip MX4 and F1 are top-notch covers. MX4 steals the show with its sleek looks, but watch out for those scratches!

On the flip side, the F1 boasts durability and a premium, scratch-free fiberglass finish. Its seals and strippings are also a tad better.

So, you gotta ask yourself: are you team “looks” or team “lasting quality”? Either way, both come with the same warranty. Your move!
