I'm not sure if this is the best forum for this one, but . . . does anybody know whether the adverse effects of sunlight on exposed auto paint are reduced or eliminated if the sunlight is coming through glass windows? I keep my 2004 VR RX-8 garaged most of the time, but I've noticed that the windows of the garage still allow the sun to beat pretty strongly on the car. Do I want to bother covering the car, even in the garage? Thanks for any input! MARK

 

Get some dark window tint film and put it on the garage window. I did a simillar thing to skylights in my house that let in way too much light & heat.

 

my garage has windows also and I thought about the same thing so I am just going to get some cheap blinds (not ventian, just the old style blinds) to pull down to shed the sun. I cannot do the window tint without a lot of trouble cause the window has panes. I think this will do the trick though! Just wanted to pass my idea along.

 

Guys, thanks for the ideas. Actually, I was also wondering if the glass in the garage windows might filter out the UV rays of the sun, making the sunlight on the garaged car less of a concern. Anybody know any relevant facts? MARK

 

No-it will still allow all the rays in unless your glass was treated with some sort of UV protection which being a garage, I am certain it wasn't. I keep my cars in my windowless garage and only drive them on weekends and after work occasionally. They always look brand new. You are correct in your concerns about keeping the sun from blasting your car daily. It also depends on how much sunlight is making direct "contact" with your car. Is it during the morning or closer to evening when the sun is less intense?

 

if you tint the windows, make sure you use commercial film and not automotive film. Auto film will make some residential windows explode when the sun heats them up.
Just a word of caution

 

Regular old glass filters out any light below 300 nm. Most of the UV range is below this number. I wouldn't worry about it since the interior would be the most suseptable to uv damage. Since the light has to travel through the window and the windows of the car, the likelyhood of damage is nearly nill.

 

Agreed. You can't get a sunburn through a window either.
