Not sure if this is the correct subform or not but I am looking for advise.

I bought a frame off Ebay that is lugged steel, Champion 2 and I would like to pinstripe the lugs. I found several different ways to apply, brush, Vintage Beugler Striper De Luxe and a cheeper one on Amazon.

My question is has anyone used the Beugler striper or a brush and what does anyone recommend for an amateur?

Picture for reference...
