I just used standard spray paint on mine, but as soon as i got petrol on it it ran down the case and rubbed it off so dont use that Was £13 a can aswell My mates sprayed his with High temp paint that you use for exhausts and it still looks ace (Y)
hava look through your yellow pages or whatever. bound to be somehwere nearish to you that will do it
if you dipped the engine casings wouldnt it cover the bit where the main bearings go then there wont fit, and it will plate inside the gearbox and inside the bolt holes. :msn1:
