For Rust-Free Storage of Cars

What is PermaBag^® ?

PermaBag® is a large airtight zip-up bag, specifically designed for moisture-free long-term storage of valuable vehicles. PermaBag protects cars and motorcycles from rust, mould, moisture and corrosion for months and years without the need for electricity!

How does PermaBag^® function ?

PermaBag® prevents rust, mould and corrosion by safely removing moisture from inside the bag, achieving ideal storage conditions of less than 50% rel. humidity, similar to that of the Arizona desert. PermaBag® is completely maintenance free, requires no electricity or other consumables. Moisture is absorbed by means of PermaPack®, a moisture absorbing 316-stainless steel cylinder. A digital Thermo-Hygrometer monitors the level of moisture inside the bag and indicates when it is time to regenerate the cylinders.

What is PermaPack®?

PermaPack® is a unique moisture absorbing cylinder capable of absorbing large amounts of water. PermaPack is drip-free, non toxic, environmentally friendly and can be regenerated in a normal household oven and re-used over and over again. PermaPack come in two sizes, 18 cm (7") and 6 cm (2-1/2").

Does PermaBag® come in different sizes?

PermaBag® is available in 14 sizes, from a small scooter to a large truck. Due to the unique shape, it is often possible to use one size for various vehicles of similar size.

Can PermaBag® be used both indoors and outdoors?

PermaBag is available for both indoor and outdoor use. The indoor version is suitable for garages, underground parking, workshops, halls, barns, etc. The outdoor version can be used just about anywhere where there is solid, non-porous ground. To make the PermaBag suitable for outdoor use, the special outer protective cover has been heat-sealed along all seams, just like professional high-performance tents and rain jackets, so that the pinholes are sealed and the cover remains 100% waterproof. This outdoor cover comes with a range of additional accessories for extra protection from rain, wind and thunderstorms.

PermaBag® for indoor use comes complete with:

• PermaBag® airtight zip-up cover
• PermaPack® moisture absorbing cylinders
• Thermo-Hygrometer for reliable moisture control
• Brass lock for security
• Practical zip-up carry bag

PermaBag® for outdoor use comes complete with:

• PermaBag® airtight zip-up Cover
• Auto-Pyjama® car cover for extra padding

• Set of Storm-Straps for stormy conditions
• Brass lock for security

Some Advantages of PermaBag® :

Some systems pump air into a PVC bag. This method simply transfers humid air through the bag, resulting in the same moist conditions inside the bag as outside the bag. Electric de-humidifiers struggle to maintain a relative humidity of under 50% and have to switch themselves off at temperatures below 10°C. PermaBag needs no electricity and functions effectively between +40°C and -50°C.
