Hi guys,
im planning to make a body panel for my car out of carbon fibre, i have some experience in making smaller parts, this will be my first large part  
what kind of things would i need to think about?
it will be replacing a plastic panel so it doesnt need to be extremely strong, 3x200g should be okay?
my parts are normally infused with in2 + a layer of gc50 (in mould)
ive been doing alot of research on this topic, but it would be nice to get the opinions of others

1. it would need to be able to withstand (up to a certain degree) stone chips from driving, would infused part with a layer of GC50 be strong enough to withstand smaller stone chips?
2. protection from heat (summer), im assuming most infused parts can withstand hot climates?
3. protection from cold (winter) , how well do infused parts hold up in cold temperatures? 
4. UV protection, what are the options for protecting the part from UV rays?
5. rain/water, do i need to think about protecting the part from rain ?

would appreciate some input

thanks
