brodie helmet, it's mainly rusty will it affect the price if i repaint it?

i bought this helmet back last year it has the original liner and chinstrap and i bought this helmet for under 50 quid but would like to restore it. will this affect the price at all as it's mainly rusty and if i would decide to restore it how should i go about it to repaint it how it would have originally been painted.

any help would be greatly appreciated

thank you in advance

Looks great... and now still original! Leave it as it is.

 

Yes agree do not paint it

 

Looks great now - but object decay is accelerating.

Most collection conservators advise slowing decay on exhibits.

Process depends on object but for mainly steel and aircraft alloys I have used a converter to slow the corrosion, create a surface protection.

Bath or Gel versions depending on best application and attached irremovable materials.

Jerrican collectors seem to swear by oxalic acid or molasses baths for rust treatment so those might be worth researching.

I imagine there are whole forums dedicated to the colour of helmets so with the all the opinions on what your tablespoon of paint should be, I suspect a 'restoration' for resale isn't going to make economic sense.
