2021 Lowrider S heat shield color
 

I just picked up a spare set of V&H mufflers for my bike and want to gift the spare set I have to him so he can ditch the factory exhaust on his lowrider S. Problem is the heat shields are chrome so I would have to prep, primer and paint the shields with VHT flame proof paint.
Can anyone tell me if I should go with matte or gloss black to match his header covers?
thanks in advance.
