Great thread Rolf and im loving the armour build
I say go for it with the hunbrol, i painted all my lids with it as you know and after 3 coats it dries hard and is sooo glossy
The good thing with the enamal paint is, as you know, it goes on without leaving any brush marks but it is flexible also.. I can sqaush and flex my hdpe lid without it cracking and coming off. I had to use a tooth pic to weather my move along helmet, no chipping with my finger nail.
And when i painted my TE2 the fragile looking hips changed to a hard thick sturdy helmet.
Im sure you will be happy with the whole suit in the gloss, it would look amazing
