Painting tank to match front fender

Hope to find some white pearl paint doesn’t have to be perfect because my front fender is not perfect but I got the front fender real cheap but I do like the color I’ll try and paint myself I always try and do stuff myself if possible may not turn out the best but I’m not looking for the best I would like to make it look like it was painted 20 or 30 years ago we’ll see if I can figure that out
