Sir big,
Here are some numbers in MY area in Texas. Today we reached 100 or 101. A stainless steering wheel read, 125 d and a bedliner covered one (black) read 147d.
Now for some real shockers.
White gelcoat 126 d
Black gelcoat 161 d
As I was saying (or trying to say) darlker colors are going to be hotter. Now if your in a norther state and your high temps are not that severe, then this may not make much of a difference. However here, it makes a big diff. Again I was not trying to say anything negative against your thread, and I will not banter back and forth with those that posted earlier, I am just stating facts!
Hope you get your boat back soon and I look forward to seeing the pics.!
