I have pretty much made up my mind to line-x the tub and saw line-x xtra advertised.. It is color matching line-x...
1. Does anyone have any experience with this?
2. What color would look good (other than black) in the tub with my white jk?

Here is the product I am referring to.

 

White would look good but I don't really know how long it would stay like that. Maybe a gunmetal color? Silver?

 

I agree, I think a Dark Gray color would look good. Kind of match the seats to the jeep.

 

I'll third the Grey

 

hmmmm... i was thinking of this...
and no one has any expierence with it?

 

Definitely the gray color like some has said. Matches the interior and hides dirt easier than white.

 

I've seen some really nice tan bedliner jobs come through. Obviously you need to have the tan dash/seats to make it look right.
If you were going for an all out "sponsored" look, a bright primary color, with seat covers that have that color inserts would certainly stand out. Not sure if you want to do that.
The black ends up being dark gray eventually. To each his own.

 

Like stated above, if this is the only color mod you will do, grey or black. Nor, IF you want to go all out, say you went with that blue you like, i'd powdercoat the differential covers, springs, and shackles the same blue, possible the gauge cluster and seat covers the same color as well.

So either simple color, or go all out to make it an even color theme
