If it's that old washing-up bowl plastic you have a problem. The best way to graft pieces in have found is to spot weld it- use an old soldering iron to fuse the plastic together on the inside. Otherwise what I have done is to roughen up the gluing surface with coarse sandpaper and apply 'brush-on' superglue liberally so that it soaks in. Then you can glue new pieces in as per normal.

To fix the wheel arches, I would trim everything back to a clean shape, then cut some plasticard roughly to fit. Glue/weld it in position, then back it up with another bigger piece on the inside that covers the joint. Fill all the gaps with a fillet of body putty. Then you can file and sand it to the correct body contours and simply recut the wheel arch to the correct profile.

Then you have the problem of painting. Most stuff doesn't adhere well to the soft plastic, but again, I have done it by papering everthing and 'clear coating' with brushable superglue. Otherwise there are special paints available in the US that have been mentioned on the forum, but I havn't got hold of any myself.

But if it's hard plastic, all you have to do is fill the arch with plasticard and recut, as above!

Hi,

I have also that great looking car with lights! (E3, without brown marks)

Plastic is very soft (old brand which was used sixties) and the problem seems to be with those cars that the heat makes it to change shape and also colour (brown marks) so i don't recommend to use soldering iron in repairing job...

Maybe melting repairment plastic with acetone would be more suitable solution. If you find same kind of plastic (also same color) maybe you'll be able to join pieces with acetone. I have seen couple of friends doing thatkind of repairments without having to paint the body.. (it requires some training). Ofcourse it is not original but looks pretty nice.

I saw acetone and differend kind of tools in deansgate's modelzone. (i was there couple of weeks ago
)

Let's hope that you'll get it fixed! Would be nice to see pics of your C68..

Best regards:

Sami

Here's my C68:

One of the ways to repair the arches - very painstaking but very strong -first lightly sand the arch, then line the arch with super glue, and the sprinkle on Johnsons baby powder. This forms a very strong bond while building up the arch. Use a narrow nose bottle to sprinkle the powder! This will dry quickly, so then add some more superglue, and more baby powder and so on until the correct size. Obviously this will have to be sanded to the correct shape and painted once completed.

This methodology can also be used to reinforce the inside of any car where it has cracked or is prone to break.

If the repair is not visible (so for re-inforcing the inside of a car or attaching a wing to a chassis for eg) you can substitute Bicarbonate of soda for the baby powder, which is more rough but absorbs the glue far more easily and forms a ver strong bond... in fact to sand it you need a metal file or a dremel ....!

hope this helps......

wow thanks mate now that seems the easiest way of builing up the arches if maybe a little slow but hopefully a great solution

For polystyrene bodies you can simply mix small shavings of the plastic (from inside the body or parts sprue) with polystyrene cement. This melts quickly into a useful putty. Of course this only works with glues that melt the plastic.

My Aston Martin accelerates very poorly, do you others have the same problem? I would think this is at least partly because the RX engine is underpowered for the 110g car!
