Help with GTR....

I just bought a Tamiya R32 GTR kit and am in the process of cleaning all the mold lines off. I noticed there are some small raised lines on the boot and down the front guards of the body. Are these lines to be removed or are they there for a reason? I looked at a pic of Primera Man's GTR and can't see these lines on his model, but they are very small so I could have missed them.

The raised lines are to be removed, but the indented lines are part of the panel work so leave them alone. It is fiddly, take your time!

And especially take your time in the left corner of the trunk lid, where the seam to be removed is right next to the raised "NISSAN" badge.
