Never seemed to be a problem on the Taco. There is enough of a curve that any "bright spot" is likely to be very small.
Now, on a vehicle with a completely
flat hood, it's a
big problem as it is like having another sun sitting right there on top of your hood and burning straight into your eyes.
This was such a problem with my Montero that I eventually rattle-canned it black:
It worked great, and although I liked the way it looked, the one time I tried to trade it in to buy a new truck the salesman was horrified and insisted he'd have to pay $500 to have the hood repainted. So I told him to shove his $800 trade in allowance and sold it myself for about $3300.
