yeah that good...but cost a bit , but if you can't get to a hobby shop ...you can just use normal clear acrylic spray paint from bunnings "white knight" ...just choose what finish you want ...matte , satin or gloss ..... glossy is harder to spray from a can and just remember thin coats ....which is hard as you can't see it... just don't over spray it ..leave it and come back in an hour for another coat.... i also found that from the spray can ...the clear coat bring out the colour abit more as well...
* Also of note is that silver and chrome paint will turn dull from the clear coat unless it water base ....
