How to remove old ugly paint job

Some time ago I aquired a new built Williams FW07. A very hard to find model. Especially in new built condition. Despite it was new built, never used, the paint job was ugly, lots of tears, wizened, yellowed and wrong color. So that state I could not accept to put the car into the Vitrine.
After an intensive search I stumbled across a nib set of decals for the Williams. Fortuna again was on my side. So the resto could start.

First of all. Since about 10 years I use the same fluid to get rid of old paint and still that time I never had to Change it. So I still use 10 years old fluid and it is still okay. I just bought another two litres to rise the Level in the bucket.

The fluid I use is from manufacturer 'TIGER' and is called 'ENTFETTER' (degreaser) and is water based. So harmless to any sort of synthetic materials. !Do not drain aluminum into this fluid - it will be eaten up quickly :-)!

So put a couple of litres into a bucket and drain all the body parts a couple of days at last. Better one or two weaks. The longer, the easyer the paint peels off. I once forgot a Body and let it drain for several month. No Problem, Body was still perfect and still is. There was not pait on the Body at all, everything came off alone. You even can drain lexane bodies with! the Stickers on. The Stickers will stay perfectly on the lexane Body!

So I had the Williams Body parts drain for a good week. See the Pictures, the paint peels off almost from alone.

Once you feel it is ok, take the parts off the fluid and clean it good with worm tap water. You may also use Soap to clean the Body parts. Depending on the time the Body soaked in the fluid you might find it useful to use a clean tooth brush to rub off some sticky paint resedue if ther is. Let it dry and if needed use a 2000 wet sandpaper to grind off some scratches or whatever. In my case I did not Need to use sand paper because the Body is unused.

That's it. Very easy and effective way to start a good restoration.

However, this fluid cannot remove nitro based lacquer! In this case maybe another product or sand paper and lot of Patience may help.
