Regarding the angle, you can never be safe because the sun continues to move. When it happened to me, my car was sitting in the same spot for hours, but happened over a short period of time later in the day. See the picture in the OP? That's typical, as you get a straight line following the way the sun moves; mine looked just like that, with a corresponding straight bubbled line on the hood surface paint.
Mine was a '63 so I think any model with a chrome/polished air cleaner could result in this.
I bought one of those black canvas air cleaner covers with the elastic around the edge, with a Corvette logo on it. Looks nice and neat at a show and I think it was about $30. Ive used it on C1 and C2 cars.

If the c1 air cleaner was perfectly flat, and it was 100% reflective (which it isn't), allowing the sun to reflect off the air cleaner onto the underside of the hood would not be any different that taking the hood off and laying it on the ground upside down in direct sunlight.
That doesn't bubble paint.
Reflected light is less intense than direct sunlight, only concentrated reflected light is the problem.

Ya know....if I can't open my hood at a cruise-in or car show I might as well stay home.
The same logic would say keep your hardtop on and the windows rolled up to save the dash pad from UV damage. Hell - just keep the whole car in the garage forever.
Screw all that....so I don't think that's the advice I'll be taking.

Maybe some are caused by the "parabolic effect of tightening the screw", but mine was focused by the circular area where the wing nut goes. The rest of the top is far from concave enough to focus a small area of light no matter how tight you screw it down..

I don't sit in a chair behind my car, I walk around to see & talk to all. BTW I also roll up the windows on my closed car, & remove the lighter from my open car. Too careful maybe.

Well now - that is what I call an 'honest' engine compartment!
I think sis's air cleaner cover gives it just the right dash of color
And I sometimes walk around car shows but enjoy sitting, BSing with my pals, etc.. near our cars. I don't see what that has to do with the hood being up. I've worked hard to have a clean, well sorted engine compartment and really don't feel like hiding it because the sun is shining.
We usually all go to an hour long dinner every Sat evening with our hoods left up and I've never had a thing taken.

This happened to my 65 during a 15 minute talk with my insurance man at his office when I propped up the hood for him to see the motor while we talked. Thing is, I knew it could happen, just did not realize how fast it could happen.

Jeeeezz - almost looks like some sort of welding bead. That's a real shame.

A little off-topic but still related to hood damage, I'm thinking a quick gust of wind could hit the backside of an open hood hard enough to release the support causing the hood to fall. This could also happen if someone leaned or bumped the hood. Inserting a bolt or pin into the open hole of the hood support would prevent this from happening. Does anyone do this?

Done it since I've had my car.....I got one of those gag "Remove Before Flight" aircraft lanyards with a pin attached and use it even in the garage through the hood support.
I saw a buddy's '62 hood slam down from a gust of wind so hard I thought sure it cracked his fiberglass - but he lucked out.

How about loosening the wing nut to prevent the distortion? Would that work?

As a followup to the recently closed thread I am posting the following:
Picture is of a hood on a 65 Corvette a friend of mine owned. The line at the upper right is the blistered paint.
It started smoking in about 5 minutes but only blistered the bottom of the hood since I closed it when I smelled the burning paint.
I think the thing that contributes to the burning is the fact that bottom of the hood is semi-flat black. If it was high gloss it would tend to reflect the heat and possibly not blister the paint.
I have told a few "new" owners of Corvettes about this and a few have ignored it and paid the price.
I currently own the car.

The line means that the hood was open for a long time, and the angle of the blister line shows that the car was parked outside in the northern hemisphere.
When I was a kid I used to fry ants with a magnifying glass. When I spray painted them with flat black paint, they would burn up just as fast as when I sprayed them with gloss black paint. When I spray painted them with aluminum paint, I'd tell one of my buds to hold the magnifying glass.
You should only take your car out on cloudy days, because, if the sun is powerful enough to blister your paint like that, then imagine how it's fading your interior carpet, drying and chalking your lakkey paint, and dessicating and cracking your seats and dash pads.
You can always install a full mirror on the underside of your hood just like the guys on TV who show how to add bling to your ride. Boyd Coddington and Chuck Barris would be proud of you!
This discussion reminds me of the death ray crystal in the old movie: Atlantis, The Lost Continent.
