Hi James When I got my car, the louvers looked AWFUL. The advice I was given was "these things NEVER need painting". I wasn't convinced. Dave Howarth swears by a simple, cheap pot of petroleum jelly. This effectively gives the louvers a permanent "wet" look. If you run a wet cloth over them, do they turn black? This is the effect you get. Personally I used a product available over here called Black Trim Wax by a company called Car Plan - the same lot that make T-cut. In 20 minutes my louvers were transformed and now look brand new. I have added another coat since then, and intend to keep doing so. There are pictures at www.delorean.co.uk/1458and2727.html Best £3.50 I've spent on my car so far. I've used it on all the black trim and it looks fantastic and covers up some minor stains I had. The hot-start quick fix is described here - I think this is what you're looking for?? http://www.dmcnews.com/Techsection/hotstart.htm Best Wishes Martin #1458 www.delorean.co.uk James LaLonde wrote: > what are the louvres made of? and how were they originally painted/color... > mine are very dull and scratched a bit. same with the non-fuctional 'vents' > behind the door and the intake vents.. > any recommendation on how to repaint/resurface these? > > also could someone help with the cold start diagnostic. i read it on > dmcnews... but... just be sure i'm right here... should i just connect the > blue-black wire to the blue-white wire on the harness that plugs into the > thermo-time switch.. and that should make the cold-start valve functional > regardless of the temp. correct? > > thanks! > james lalonde '81 vin001697
