Back to the main thread on the build-up of this machine.
I wanted to achieve a special finish to the bodywork on this project, and I chose to use Candy paint. This type of finish requires multiple layers to achieve the desired effect. The end result is amazing though – a kind of semi-transparent blue with a real depth to it.
The basic steps are as follows:-
1st prep the plastic bodywork. This involves stripping everything down. Removing the locks and any other metalwork. Thorough cleaning (these machines have been in bookies for years and they smell of cigarette smoke before they are cleaned). I have tried everything from washing up liquid through to commercial plastic cleaner but I find the best results come from using plain old “Cillit Bang”
http://www.cillitbang.co.uk/ to get the dirt off.
Once the bodywork is clean I use car body filler and sandpaper to remove any deep scratches or dinks. When that is done I go over everything with 600 grit wet and dry to provide a key for the paint.
When spraying plastic it’s very important to use a good quality plastic primer or adhesion promoter. This will key into the plastic and allow the paint to stick. Without it the whole paintjob could peel off! To make spraying these machines easier I made a CandyCab spraying rig. This is simply a heavy duty engine stand with a custom made plate – onto which the CandyCab chassis is screwed using the existing holes provided for the castors and levelling legs. It works really well and allows me to rotate the chassis while I spray without touching the bodywork.
Once the primer is dry, a quick rub down with 1500 grit wet and dry and you’re ready for the silver basecoat. I usually spray 3 layers of silver to get a good depth of coverage. Any silver will do – but try to get the most “sparkly” for best results.
After the silver comes another rubdown with 1500 grit wet and dry, and then it’s on to the complicated bit . Now I’ve been spraying paint for 20 years, starting on cars and motorbikes and moving onto arcade machines in recent years. I thought I was pretty good at it until I came across Candy paint! This stuff is a nightmare to get right on a 3D object. Doing a single flat panel would be easy, but with the multiple curved surfaces on a CandyCab getting equal coverage on all surfaces is not easy.
The blue candy concentrate is mixed with 2K lacquer then sprayed in very light coats to build up the desired colour. I estimate it took around 15 coats to get the right depth of blue and still have the silver showing through.
Once I was happy(ish) with the blue the whole job was sealed with 5 coats of high quality clear lacquer to provide a hardwearing finish. A lot of work – but a great result.
