BLOCK-IT 400 Evolution

BLOCK-IT 400 EvolutionFour layers of high tech protection!

Unfortunately, paint finishes are not customized to the climate in which the driver lives. Certain conditions are worse for your vehicle than others. Extreme heat or cold, frequent rain, salty and humid climates, and very dusty areas all play a role in the demise of your paint and clear coat. Protect your vehicle in any weather with the outstanding protection of the Block-It 400 car cover by Covercraft.

The Block-It 400 is made of a four-layer fabric called Technalon/Evolution 4. This multli-layer material is 100% sunproof, breathable, and 90% water resistant. It blocks out ice, snow, rain, bird droppings, mud, strong winds, and animal footprints. The Block-It 400 resists tears and punctures so sharp debris never touches your paint. The dense material absorbs the impact of falling debris better than any other car cover fabric so the finish is protected from dings, dents, and nicks.

The Block-It 400 dries quickly because the fibers do not absorb moisture. Microscopic holes in the fabric allow moisture to evaporate from inside the cover should you put a wet cover on your vehicle after washing it. Mold will not grow because moisture is allowed to escape.

The two central layers of the Technalon fabric micro-filter dust and pollution through a melt-blown fabric barrier. The Block-It 400 provides exceptional dust resistance, even the tiniest particles.

The BLOCK-IT 400 is like sunscreen for your vehicle!Block-It 400 uses the same type of UV protection chemistry found in clear coat paints. There are two factors that enable the Block-It 400 to have superior protection:

Fabric Construction: Thickness And Pore Size are critical parameters for increasing UV resistance. Block-It 400 has four layers of protection: Two layers consist of microfibers.

Finishing: Kimberly-Clark Uses a unique two Part UV protection system: UV blocking and UV inhibiting chemistries.

The Block-It 400 is a heavier car cover because of its thick, 4-layer fabric. It’s best for long term storage inside or outside, but can be used daily by someone familiar with car covers. Covercraft provides a 4 year warranty on this cover.

The BLOCK-IT 400 at a glance.Advantages:
  • Naturally Moisture Resistant - Acid rain, industrial pollutants, tree sap and bird droppings will not harm the fabric.
  • Dries Easily - Moisture is not absorbed by the fabric fibers.
  • Breathable - Allows air to circulate through the fabric.
  • Dust/Pollution Barrier - The two middle layers of melt-blown fabric act as a filtration barrier against most airborne pollutants as small as 0.1 microns (smaller than talc).
  • Impact Absorption - 4-layer thickness absorbs impacts better than any other vehicle cover fabric to help protect the finish from nicks, dings, dents and scratches.
  • Double stitched overlapped seams
  • Neoprene elastic hems – the elastic in the front and rear hems helps hold the cover in place
  • Reinforced, non-scratch grommets – use a tie-down rope (supplied) or a vinyl coated cable and lock (optional)The four-layer fabric provides durable protection indoors and out.

    Antenna openings – All Covercraft covers are made to fit vehicles with retractable antennas. If your vehicle does not have a retractable or removable antenna, you will need to cut a small opening in the fabric. Call us at 1-800-215-4460 and we will include an antenna grommet with your cover at no extra charge.

    Mirror pockets – Patterns for vehicles manufactured before 1965 may not include mirror pockets. In some cases, the cover will fit over the mirrors without pockets. If you need mirror pockets, they can be included but they will not be sewn into the cover. Call us for details. This applies to some pre-1965 models only.

    Cleaning Insructions - For general cleaning, spray off the cover with the water hose while it is on the vehicle. Allow it to air dry. To spot clean stains, spray the spot with Simple Green All Purpose Cleaner. Agitate the spot lightly with a sponge and rinse.

    To wash the entire cover, put the cover in a large commercial washer without an agitator. Pour a ¼ cup of Simple Green into the washer and allow it to fill. Then put the cover in. Run the cover through two rinse cycles to be sure all the cleaner is removed. Air dry. (WeatherShield and FormFit covers can be dried on regular heat in a dryer. Polycotton and flannel covers can be dried on low heat.)

    You may also clean the inside of the cover by turning it inside out on the vehicle. Mix one ounce of Simple Green per quart of warm water and spray it onto the cover. Rinse thoroughly until no suds are visible. Air dry.

    For added security, add the Car Cover Lock & Cable to your purchase. The cable is vinyl-coated so as to thread through the grommets without scratching.
