Default Window fog

How do you guys that have stripped cars, no hvac systems keep your windows from fogging? I want to keep my car as light as posible but still be able to see when i have to drive the car in the rain or when it gets a little colder.

Scotts no fog cloth, it's the only thing i ever found that really worked for preventing fogging inside motorcycle goggles.

Some say that he navigates the track by feeling where the clag is, and he is so good at it he can set track records even when his head is up his ***. All we know is, he's called The Hustler.

I have been using a Rain-X like product, on both sides of the windshield, and that does the trick. Granted this is in South Texas and not San Francisco but it works.

Rain-X no fog stuff. I've been using it for a couple years and it lasts about 4-5 months at a time, provided you don't clean the inside of the window for that long.

On a related note, how much can that plastic possibly weigh? The PO of my car stripped the hvac tubing out of my car, presumably for weight savings, but I figure it can't amount to more than 6-8lbs. Frankly I wish I had the ducting back in there.

Well this is within the context of a stripped down track car, that is nothing stays unless it is absolutely essential. Removing all of the HVAC items is a lot of weight reduction. I removed it from my current track car, and will be removing it from the next one, along with the entire dash.

Timely subject...I am debating this as well. To me it's just ugly when the dash is no longer there...all that nasty hvac crap! Having said that, I may still leave it...

The fan and empty heater don't weigh much, but add the water and all the small things around it. The cooling system becomes so much "purer" with only the engine and radiator (maybe a oil/water heater/cooler).

Stuff that is not in there will not break

Personally, I'm too fond of a heated windscreen to be able to see better in the rain races. For some reason open top racing makes the inside see some spray too... (and it's not me, I have the visor down )

Catch22. If you drive faster, the airflow over and around the windshield will defog it, but in order to do that, you have to drive faster without being able to see. I'm really only half-joking here - driving faster will legitimately defog the windshield.

The solution is to simply never drive slowly.

Serious answer: Rain-X, or leave the HVAC in for the defroster.

That hvac tubing weights nothing. its paper thin abs. I just had a 90 dash apart to clean all the junk yard dirt out of it, then refoam and space tape everything to seal better and rattle less. I think emillio has the real anti-fog/frost solution with the defroster of doom.

Well then that makes sense. I'd pull that crap out, too, in a track car.

Maybe just leave some of the tubing, and put a fan with a on and off switch? Hmmm dam you chicago weather.

run a hose from any high pressure area to inside windscreen.

all you need is air blowing across the inside of windshield. do not need to be hot air

I know some racers who use dawn dish soap on the inside of the windshield wipe it on, and wipe off all you can with a clean rag.

A naca duct in a corner window and some tube would work good I would think.

Or rainx anti fog.
