warped hull on Leapord 2A5...

I am currently building Tamiya’s Leapord 2A5 model. I have noticed that the upper hull is warped, but I’m not sure if I should try dipping it in hot water and correcting it, or gluing it down bit by bit and straighten the curve that way. Plz give me your advice

On the box and the instructions there should be directions on who to contact to replace the warped parts free of charge.

I would try glueing it and see if it straightens out first. It should straighten out just fine once it mates with the lower hull.
