Just to Share how i paint. Its is a pretty cheap work. I bough;
-OMNI Acrylic Color white (AC12P#50), Yellow Ochre (AC12P#5) and Black. each one for 1$. (bought at Popular, not sure every popular have it. I bought in North Point)
-a Bag of All purpose Brush assortment (21 Brushes)3.9$.
-a pack of Laser printer, water, Clear "Decal" paper. pretty good stuff although i just need a little bit of it, i bought a 10 sheets pack to use in other places like iPhone etc.. (how to use? can search on uTube) about 20$ from eBay

step 1) mix the first three color until u get the color close to 70-200. main color is white then add a drip of black to become a little gray. in my case, not sure because my 70-200 is too old or what, a bit yellowish. so i add a little bit of yellow. Note: can add a bit water but not too much or paint will sag. Acrylic paints can dissolve in water before dry. While dry, resist to water.
step 2) put some tape to demarcate the area that don't want to be painted.
step 3) take a deep breath and paint using brush. (that would be good if u have an air-brush with compressor so that you can spray. much nicer work) and let it dry for few days
step 4) use decal paper to put the logos like Canon, 50mm etc.... (find online for logos)
Water-Slide Decal paper. How to print and apply decal. - YouTube ( this tutorial show u how? they use inkjet printer so, have to spray a layer of something.. in my case i use laser printer so, not needed)
if you see my lens carefully, there is a typo error. 0.45mm/1.5ft instead of 0.45m/1.45ft
step 5) Here we go, a step that can't be missed out. Put two run of tape with about 2mm of gap for the red line. and use a red permanent marker to draw the red line.
step 6) Share with CSer for better ideas.. LOL
