I and am helping a friend build a Tomahawk BAE Hawk. The one piece clear canopy plastic arrived with two packing creases that will not push out.

Does anyone have a method of pulling out the creases and returning the plastic to the original shape?

Thanks

Hi.

The creases may not disappear even if you can pull out these creases. What I have tried before on a very minor dent
was dip a fine weaved rag in boil water, and or carefully soak the damaged part in boil water, but keep an eye out for
melting of the plastic. After that, i tried to push the dent out with the hot rag. It did help, but I couldn't get the creased
line to go away. Good luck.

Thanks I wil give it a try.

Heat will usually return plastic to its original shape . Heat lamp or heat gun . Heat lamp would probally be the slowest ,but safest. Heat gun will work but just do not get too hot.
