    For the horizontal areas around the engine, by emmission tags, etc...

    Anybody found an off the shelf brand with correct color and sheen?

    Thanks

    Use SEM trim black. You can find this at your local parts store. It will come in quarts and spray cans, both will work great! I have used this on many show cars and you will love it!

    I don't know if this is really "correct", but Eastwood has "Chassis Black" and "Underhood Black" spray paints that have a semi-gloss appearance that I think look appropriate.

    Yes, I've used the Eastwood products on tons of muscle cars, but their blacks are not quite flat enough for the 308. OK for the chassis and wheel wells, but the inner fenders seem different.

    bpfordfan, are you saying you have used the SEM trim black on Ferraris and the match is good?

    Without doubt, Wurth's water-based black undercoating. You can spray or brush it on. It goes on gray, then dries to a PERFECT satin black match. I've detailed the hood and engine bay of my 328 and they look great.

    I did some digging around on the Wurth's products and I think you are right on. Where did you buy it? Are you using their product called "Stone Guard" for use on chassis and wheel wells, etc...?

    I believe its called Wurth's SKF? I can check tonight. I used to get it from carcareonline.com, but I just checked their site and they don't seem to carry it anymore. I'm sure a call to Larry Reynolds would clarify things.

    I'm not kidding, it really is indistinguishable from the original, and, if I'm not mistaken, its actually the OEM product used by Ferrari...

    Is this the one?

    WURTH SKS STONE GUARD...Matches OEM Porsche, BMW, Mercedes and other European auto makers' "body schutz" or undercoating. Can be built up because it doesn't run on vertical surfaces. SKS is water based, fast drying and flexible when dry. May be painted or left as applied. It is best applied with a Wurth SKS Gun, but may be applied with a brush.

    11335 Wurth SKS Stone Guard - Beige, 1000 ml bottle
    11336 Wurth SKS Stone Guard - Black, 1000 ml bottle
    11337 Wurth SKS Stone Guard - Gray, 1000 ml bottle
    11338 Wurth SKS Stone Guard Spray Gun

    SKS. That's it. I use a foam brush w/ a dabbing motion, not a brushstroke.

    Len S,
    Thank you, thank you, thank you.
    I finished one of my wheel wells last night. Scrapped out all the old undercoating, gunk and paint overspray. Wire brushed, sanded, etc down to perfect bare metal. Then I used the Wurth Stone Guard that you recommended. By this morning it looked perfect, brand new and factory correct. Stuff is great. I appreciate the tip.

    One other thing: I learned the hard way not to keep this product in an unheated garage. It freezes into a block of gray ice! Luckily it appears to thaw without any negative effect.

    They now have the stuff in 14 oz spray cans, which I used. Couldn't be easier. Will take pics this weekend.

    I used the "underhood black" around my engine bay and it looks like the original. It's been over two years now and still looks new. You can see it on the left side shelf where the stickers are, and metal piece on the underside of the engine cover that sits above the engine.

    I had to add my experience with the Wurth Stoneguard. The stuff is a dead on match for the under-hood and under-door coating. I used Len's dabbing method above but found I was getting uneven results. Instead I used a combination of both; lightly dabbing while moving the foam brush along the surface. You get a much more even coverage. Oh, and do NOT go back over anything until it is completely dry! I tried doing that and it just messes up the look. Also, be careful not to let too much get on the brush. This stuff is thick and can quickly cover up the little golf dimples in the surface.

    Joe's right. It takes some practice to find the right combination of dab and stroke motion. Also, over-saturating the brush and pushing too hard will create ridges that you definitely don't want to dry. I found that cleaning the brush as I go along helps, especially since the product is water-based. Or just keep a pile of clean, extra brushes handy...

    So this Wurth stoneguard, is this what you guys are using on all the framing, all of it? Under the hood and deck lid too?

    Yep, seems to match everything. I touched up the wheel wells and the rockers and I am in the process of touching up the engine bay right now. The stuff takes "about" 12 hours to dry so now I can go back and see about touching up the spots I tried to touch up too early yesterday.

    Len, how did you handle the flat areas on by the emission and oil labels?

    Joe, pretty much the same way. At first I thought that I would have to touch up all surfaces to get an even finish, but when I discovered that the product dries to a perfect match, I scaled back and only addressed areas that had thinning or chips. A perfect example is the rear deck bolts, which were pretty scarred after removal for a major service. I touched up the bolts and surrounding area and stopped there. Luckily the flat areas you mentioned are in very good shape...

    Artvonne, yes, all the framing, underside of deck lid and front hood, wheel wells...
