Tamiya Mercedes DTM ?

Hey everyone, just trying to finish up my CLK DTM and had a question regarding the taillights: The instructions state to mask off the clear portion and paint the outside of the lens. is this right? Doesn't painting the inside usually look better?

inside is better yes, but paint may run below the mask becose of the small detail on it. it's quite hard to do, I did it all red

only way to get it right is to paint it from the outside, with the mask and using an airbrush

I prefer to mask and paint both sides, I use an airbrush because you can get a smooth finish on the outside and the color builds up quicker if you do both sides. If you don't use an airbrush it is better to paint the inside only.
