I'm looking for a new right rear side window to my F40, if anyone have a spare.
I'm watching ebay daily.

Hi Egon,
did you already try to get the window by Stephane Pedaggi@scaledetails.com? He seems to have some spare parts for the Ferraris.
But if you are not really in a hurry for the piece...take your time and go for some fishing in the bay. Made my experience, that your fish is on the hook, when having some patience.

Will watch the offered parts and tell you. Scout promise.

I have been watching for a couple of years. Windows for the F40 come up very rarely and usually sell for over 100 US dollars for the full set.

Perhaps the solution is to buy a new kit and part out the rest. he1he New ones show up more often, but go for really big numbers.

A group F. was just sold on ebay, vent for 42 €.
Maby I just try to replace the one broken window with a 1mm lexan.

That converts to $56, a much much better price than I've seen on the US eBay. :(

Can't hurt to try making the window from Lexan. If it works you've gained experience making windows and saved a few Euros. If it doesn't work, you're right where you are now. I say, Do it!

Problem solved !
1,0 mm lexan in the oven (80-90 c) a short time and it's soft enough to be pressed to shape in the mold, that's made of bondo and shaped of the original window with oil on so it won't stick in the bondo, but it got killed by being to long in contact with the bondo as you can see.

Spray the bondo with a good primer sealer and paint with a high gloss paint let cure for a few days then wax with a good carnuba paste wax..That should stop the crazing..

Using a female mold you might run into sizing issues if you prime and paint the mold. Being as size does matter I might try to use the broken window itself as a mold. Glue it together and fill the exterior curve. Mount the window to a good solid backing from the inside and then prime paint and wax that. Use hot or maybe even boiling water to warm your Lexan just enough to match the curve and retain it's shape as it cools. Now trim to shape and polish the edges. You should be golden...I hope. Best of luck and let us know what you come up with!

Thanks guys.
No need for paint or wax, the new white window still has the protection film on it, the clear one was the one I made the mold with and this reacted with the bondo, despite it had the oil on to protect it, but it didn't work as expected, to long time in contact with the fast curing bondo and it stick to the window, some other protection ? is needed with this kind of bondo moldmaking, the new window fit perfect.

Done, done and DONE! Right on man!

I found out that polyester bondo can be made more smooth with the liquid polyester to fiberglass, they mix very well, the more fiberglass polyester you ad the harder the endproduct get, and you can use the hardner from the bondo, the same amount as normal.
With this you can make a more detailed build up like thin lines.

Now that is interesting enough to wattant some expirimantation. Thanks Egon!

I'm doing my windows with the same method. The mold is polyester; 2 k bondo is added if needed (it's all the time needed!). and the whole is put in the oven. If the plexiglass has some markings, it can be sanded and polished.
