Well let's get some pricing info from Dave first. You can do a surprisingly good job with rattle-cans, so I wouldn't rule those out - plus you can always get it painted 'properly' later. Volvo's own spray cans are excellent, and cost about £12 for a set (colour and lacquer) in metallic colours. With care I think you'd get the valance done with two can sets. A Halfords can would be a lot cheaper - practise (and smoothing the colour out once sprayed...) is the key! Alternatively a bodyshop shouldn't charge more than £50 to spray it for you - possibly a lot less. I think Dave might be able to help out there.
There is a group buy on 300 series valances happening as we speak...£80 a pop. Post in here for more info...
