Hi sydney kid...I have a sandblast cabinet so i blasted them with glass beads first then they were polished to a mirror finish...next the surface must be free from all polish and foreign matter(its extremely important...more so than with other paints as this paint is transparent and if you get fish eyes or silicon spots then you have to start again)The paint is 2k and must be painted in a completly dust free enviroment as any dust or crap in the paint will show up and a big black spot( this is due to the candy gathering around a speck of dust..therefore a darker patch in that area)The heavier the material is applied....the darker it becomes as i said in the above post,very shapey parts are very difficult to get the surface looking uniform.The part should then be baked at approx 80 degrees....obviously its not spray can material...its a 2K product by a japanese company called ROCK the colour available are very wide from blue purple gold green red and can be mixed to acheive a custom colour........Its important to use the correct material as normal candy will not stick to the polished surface,i guess some adhesion promoter may make it stick but i am unsure on how this would affect the finish......I am quite sure this is the product that Nissan used on there 34 GTR engines from that factory as when i blasted it off there was no primer or nothing under the original paintwork,I remember i painted some R34 covers for a 34 that was repaired when i was in japan and 99 percenet sure its the same stuff i got from the nissan dealer........the covers could have been painted over the original finish but a inferior finish would be acheived
Hope that helps
I still have some material left if you need a set done
