ABS stormtrooper helmet needs fixing (wrong vacuforming)...how to?

[chameloon]

Hello,
I have this helmet, and one of the lens openings is slightly bent (right one, on the picture). What can I use to push down the plastic and give it back the correct shape and curve? (I know some original stunt helmets have this particular defect, but I'd like a more symetrical design)
Shall I use a lighter to heat the plastic? A heat gun? Won't I screw the rest of the helmet shapes using a heat gun for such a small surface?
Thanks for help!

i believe a modellers sealing iron or similar is what you require

i wouldn't use a lighter or heat-gun

If you don't have access to a Hobby Iron, you could try dipping it in hot/boiling water. That is how I reshaped my calves. If not, then a heat gun VERY CAREFULLY

Maybe try using a heat carefully on warped area maybe it might work.

I second using very hot water to soften it, shape it, then ice water to set the shape.

Thanks a lot, will try very hot water!

That bump is there on purpose... The original helmets had that (albeit not quite as pronounced on every helmet):

Yes, I've noticed that. But on mine, it is very pronounced, so I'd like to have it less visible...

I would first trim the eyes out more. You have more of a "return edge" on there than most original lids had.

Look at the original RS Prop Masters helmet for instance, there's hardly any edge left:

Same here, Sandtrooper lid in the archives:

You're right! I will start with that. Thanks for the eye-opener (pun intended )!
