By the Way, does anyone tried to geht a Double-Visor Look with this Sanding Pistols, that are used to get a Ground free of any Paint?
That Pistols can spray any Sort of Sand, from very small to big Corns. I think they have a adjustable Sprayline to geht those Visorlines on the Helmet.
And in the Case they dont do it so as i think, taping the Visor should be a second Option, let only the Visorlines free and sand it.
Hmm...that reminds me on a second sanding Method that uses Flour, in the End it looks like that:
The Materials for that are very cheap, you need only Water, a Bristle-Brush and a special Sort of Flour, dont know what "Bimsmehl" is called in English
Mix the Flour and Water until it looks like Pap und then Brush it for about 5 Minutes, change the Way of left to right and right to left every Minute or every Brush, it doesnt matter.
Should try it, normaly this Method is used by Casemodders for theyr Casewindows and doesnt have a Dremel or something.
