I tried extending a thread on the originality forum, but not much luck there:

http://www.914world.com/bbs2/index.php?showtopic=152778

Anyone have photos of an original or 100% properly restored 914-6 showing the rear fender wells and bottom side of the rear trunk? It seems like black undercoating is never right as it was just applied by the dealers or ports (or something), and besides it's ugly.

So, it seems like the good options for these areas appears to be:

1. metal -> primer -> body color paint

2. metal -> primer -> grey PVC undercoating

3. metal -> primer -> grey PVC undercoating -> body color paint

Or ?

This was answered in the weenie forum so why i it here ?

FIRST 6's were done in the same factory as the 911 and had the SAME PVC undercoating the 911's did. I posted pics of this in the CW thread. I also posted many pics of the underside of Cairo's car in his build thread. His underside was one of the cleanest most original ones I have seen, even still had the factory gold overspray under the aftermarket black coating.


1 bare metal
2 grey primer
3 PVC undercoating
4 overspray from body painting


Mark, I also have that gun and can't get it " just right " I just recently got the BIG gun from WURTH that is supposedly the correct one for duplicating the factory finish. I'll post results once I get time to play with it.

Also, WURTH SKS has for years been the go to for factory undercoating, but recently they stopped selling it in grey and now only sell it in black (IMG:style_emoticons/default/dry.gif) I have found another brand that is in the proper grey, and will be trying it with the new gun. This stuff is also half the price of SKS and was recommended to me by a Ferrari restorer. I'll try and remember to take some pics of both tomorrow

Please do, I need a bunch of this for my current project and have been hoping to find SKS gray on someones shelf, yet to find it. (IMG:style_emoticons/default/headbang.gif) But if this stuff works just as well then Im in.
