does anyone know where i could get a kit or best type of paints / primer etc.

not going to the cost of powder coating and want to diy it , but do a proper job.

 

Hammerite is decent enough.
Refurbed a few sets of 4 pots and they cost about £20 a set so may be worth finding a powder coater.

 

how much do you think powder coating two 4pots and two 1pots would cost

im going to buy ss piston refurb kits probably from scooby works , they cost around £180 for all 4 , they also do refurbed calipers at a cost of £400 for all 4 fitted with ss pistons and powder coated ,

im not sure hammerite would give as good a finnish i'd like im thinking more primer paint and clear coat , its as much about doing it myself as it is the price

 

£30-£40 perhaps.
Foliatec make a decent caliper paint set.
You could use Halfords spray paints as they do primer,colour and clear coats.

May be worth doing a search as this topic has been posted a few times :-)
