those revoltech stuffs are basically made fr pvc (check the box, usually they'll indicate the material used for the action figure)
if it's pvc, try get a metal primer (from either gunze or tamiya)
after coating it only u can paint it easily. otherwise the paint hard to stick..
Added on May 29, 2008, 7:40 pmbro.. dun do like dat if u intended to have a clean line.
when u use markers, it's mean to be wipe of when dry not wet.
if it's wet, it's hard to prevent smearing and smuldging..
most gundam markers are easily removed by erasers, worse, use alcohols (or methylated spirit) if u only do lining on bare plastic.
for painted surface (assume acrylic), better use enamel wash/inking.
if u painted with acrylic and stil insist on marker lining, get it top-coat with gloss to protect the paint layer.
then only do lining, clean up with alcohol (be gentle), finish of wth matt or satin (to your liking)
hope it helps..

all surface has to be smooth preferably gloss if u intend to have a clean line.. rough surface is very hard to clean up..
ah thanks for this useful tip. now i know whats goin wrong with all the smearing and smudging (if you checked my posted exia/kyrios on the in progress/gallery thread, from the high Q pics that allow clear close ups, the smearing/smudgings are pretty visible
