Just wondering how I would go about blacking out my tailights.

 

Use some vht night shade (ebay)
First wetsand the clear off the taillight with 800 to 1000 grit
Then use some wax and grease remover
Start spraying the night shade spray lightly to avoid runs let it dry and put on few more coats.
Then use 1000 wet with soap get the tint smoothed out
And then spray about 4 coats of clear Here are my taillight after i black my taillights
