That’s really poor, especially for the price! Personally, I would send it back. Not so much about the inside roof but the centre pillar, the sides are awful, it’s like paint has run. It’s a lot of money for what it is so I’d send it back. Also by getting it back, they can see what the factory is putting out! Only just found you and your channel as I’m looking to start a little tt layout myself! Keep up the great work!
