My Garage is pretty much airtight, but the dehumidifier still finds 5 - 10 lts PW.
So yeah its worth doing, but remember to have a 4 inch vent pipe on the exit side that runs to the other end of the garage to ensure decent circulation.
Still doesn't quite solve the tarnished disc problem though. Anyone with a solution to that problem I would love to hear from! thumbup

Are they really needed?
Think my garage is a nice cosey place and the car will be in the carcoon over the winter months, will it still benefit?
I have no knowledge on the subject, not trying to be funny at all.

A carcoon will certainly be good as they are designed to make any tempreture changes gradual but the air within the carcoon will unavoidably carry moisture, even on a nice dry day.
Whilst sudden tempreture changes are the cause of much damage through varying degrees of expansion and retraction of differing attached materials (metal and paint for example)it is the moisture which causes the rust. This is why in many locations that have hot days and cold nights "crazed" paint is a lot more common. For the sake of a couple of hundred quid you may as well take all the precautions you can IMO.

When you get one, look for one that allows you to vent the excess water out of a pipe which you can run outside the garage. You'll soon get p*****d off emptying one that has a collection tank even if it is 10,15 or 20 lt. The other option is either mount it at a height or stand it on a bench then attached a vent pipe to the collection tank and run that outside. Also try and find one that has an auto defrost. As they work on the same principal as a fridge and the moisture from the air collects on the freon? chilled grate. In winter these can easily become blocked with frozen water that has been taken from the atmosphere rendering the unit pointless. (Alternatively heat the garage!)

Yes, I use one too, and recommend it. Otherwise fast temperature movements will leave lots of moisture on your car's metal.

Yup, I have one. Nothing big or fancy, a 100 odd quid job, but its suprising how much water it removes!

I have one, it's for a 5 bedroom house and cost £80 from Homebase. Has a 2lt capacity but the option of a drain out if I could use it. I've had it running for 2 years solid except for a few weeks when I've been away.
I keep all my workshop manuals in the garage with no problems and have never had any insects/spiders etc in there. They obviously hate the dry!
Ok so I have to empty the bucket when it's full but it's at table height, works better there, so not a problem.
Just make sure you have one with an auto-shutoff.

my work involves dehumidifiers in large buildings, i had a small one in my garage to test. first problem is below approx 5 degrees most freeze up and don't work. second problem is most garages are not air tight so you are unable to stop damp air entering the garage. i would recommend a carcoon in most situations.

Just bought one. Good piece of kit.

Asked elsewhere and wise to keep levels at around the 50% mark. Prevents rusty build up but also stops leather/rubber drying out etc.

I run a Mitsubishi MJ-E16-S dehumidifier piped down a drain. (also from dry it out.com). Four radiators in the garage. Fits three cars two bigguns and the Porsche. I also use three black deioniser pyramids. The garage door is a 40mm thick and insulated. The garage has been plastered and painted with spot lights and flourescents. I leave two small windows open for ventilation. The end result is perfect with no tarnished brake discs and my HD still shines as good as new. The pyramids keep the dust down to almost zero. Don't ask me how they work but if you look on the floor where the pyramid sits they have a thick black soot around them that you cannot wipe off. The missus would prefer the back part of the garage to be converted to a dining room. As she can't cook I would prefer part of the kitchen converted to more garage space.
