Spoiler or no spoiler

So its coming time to do my body work on my teg, after the turbo. My spoiler has large rust spots around each post of the spoiler where it touches the trunk. Should i ditch the thing? or put on my DA GSR spoiler with the light on it, and just do some real body work?

Also what would you recommend to put on side moldings? my rear pass side molding rusted off, is there any good glue or anything i should look into?

i think wingless. it’s a hard decision seeing that i have seen both and they all look uber hot when done right, but i think since body work is being done, have them welded shut
