Decided to go ahead and give it clear coat since I have gotten good feedback on here and also on other sites. I put the visor in with tape so it can be removed later if I wish.
Here is a picture of it after being sprayed:
Now the next step is to buy a Peter Weller face cast and attach it to the inside of the mask.
I'd say the colour on the helmet is a more RoboCop 1 style finnish..looks very good..and after looking at that link to the helmet on Ebay, i'd say thats a very canon looking helmet.
