Peterjon, Southend slot car club have a web site giving instructions on moulding cars, and Southend is right next to Westcliffe.

I will also give the email address of the guy who made my Mega-G F1, he is moving house at the moment so will likely be out of reach for a bit.
I am sure both will be happy to discuss the properties of what they use, so you can find a UK equivelant. To my mind too many resins, at least in HO, are way too heavy to be raceable, but that does not apply with these two gents.
That reminds me I must weigh the Williams....

I crash too much during racing to make a resin body viable for me to race, I need a crash proof body for racing.

I use Tiranti T20 silicone and G26 two part urethane resin. polyester is too noxious to use my dog used to suffer lying on floor directly above cellar were I was casting and the mix ratios are diffficult. also look up Techsil as I use them for some advanced resins for tyres, resin dyes and crystal clear resins(not found a good one yet). Does this help? don,t think its a trade secret but we all build up a bank of casting tricks from experience . I even ran a day course up here in Manchester on Casting last year.

I think they are a bit on the small side? If they are the same as the stuff that was marketed as Kyosho 2-3 years ago.
Just to throw something out there, Roger Corrie is the master of adding a material that expands the shell by a set amount. I think there is a material that contracts them too. So if the donor body is too small or too large you use a set amount of this stuff to end up where you want to be.

Another, more expensive way is to cover the pattern with sheet wax, mould that, then use it as a bigger basic pattern to detail. We used to use that method in the full size prototype car industry.
