I removed all HVAC a long time ago... i hope those late, chilly, summer nights at the strip dont screw me on da drive home or on the track! meaning the windshield fogs up and there is nothing i can do about it!
any known remedies to prevent internal fogging? im almost considering making a frankenstein defrost heater out of thin sheet steel and a space heater and putting in in place under the dash (Yes, i know. dont say it- WHY DID YOU REMOVE IT IN THE FIRST PLACE!!). i did that cuz i didnt want the A/C system (t top )
and the factory box looked ugly as hell just sitting there in the bay.. so i used a large mallet to smash it out since i didnt feel like dealing with dash removal

 

rain x makes a nofog or defog i use it in my full face helmet works awesome

 

ooo nice i need to get summa that..
regular rain x works great, however, you have to apply it a lot, cuz it seems to wear off after a while, cuz it dosent work very good... and when you have BRAND new blades it just smears the water into a ton of tiny tiny drops...i suppose its better than a slurry wet map of a windshield..
