A reissue of the Scirocco kit would be fun. With some kit bashing using the Revell GTI and Cabriolet kits it could be updated quite nicely. The aftermarket - that wasn't really around the first time these kits came out already has a lot of stuff that would be good.
The rear suspensions that the early Golfs and Sciroccos had was very simple - but also very effective.
I would definitely say you need to add a build card. It also needs to be typed with good English so it is easy for people to read and understand. Adding a build card helps judges as it gives extra information (no one is going to know everything and they certainly weren't there when you built the model) and viewers get the opportunity to learn more about the model if they are interested in it.
Keep it brief, this may mean if you have done a lot to a model you'll just be mentioning the highlights (or, in other words, what makes the build different) as people don't want to read reams of information. Judges often don't have the time to read a lot anyway. Add a few photos, but once again, don't overdo it.
Entering competitions pushes you as a builder and I enjoy entering them. However, the same model will do well in one but not place in another (sometimes up against the same competition) and judges will have opinions so don't waste time getting frustrated when you do not place in the top 3 (or whatever you goal may be at a particular show). Be pleasantly suprised when you are successful - there are a lot of good builders around and judging shows is not an easy task.
If you want to clear coat the decals put the decals on next and clear coat them (you may need to give the next coat of clear coat a light going over with polishing cloths to get rid of orange peel). Use the novus and wax but keep away from areas you'll be spraying different colours. Putting the wax on before masking should reduce the chance of the masking tape pulling the paint off. Mask the model around where you want to spray the headlights etc. and then use paper towel to cover the rest of the model (saves tape and is quicker).
The plastic needs to be really smooth before spraying on the primer (which I usually smooth with a 4000 polishing cloth used wet). I often don't use primer and just spray the Alclad gloss black base straight onto the plastic (if you're not sure test some on the sprue that comes with the pieces you are using). Make sure the black is nice and glossy and spray the chrome on about an hour after you have sprayed the gloss black base.
The really important part is to spray the chrome on at a very low pressure (a gravity feed dual action airbrush is best for this) and gently mist the chrome on until you see the effect you want. It is very easy to overdo it and end up with a silver finish rather than a reflective, chrome-like finish.
I usually open mine when I get home - I'm too good at losing things to do otherwise! I then put the decals in a safe environment as where I keep my kits is exposed to big changes in temperature. I also make sure things are packed properly - very important when getting second hand kits as it is important to avoid clear and chrome parts from being scratched. As other people have said tyres can also be a problem so I make sure those are separated from other parts.
It is important to check the contents quickly so mistakes can be retified more easily. Having heard about the problem with the GTI kits on here I checked mine as soon as I got it today!
The main reason is that it is fun to look at a new kit and think about what the build will be like. I'm also guilty of getting kits out again just to have a look at them or sometimes to see if a kit bashing idea is viable.
I like your project Bill and I'm sure the car's owner will love to have a model of their vehicle. I doubt they'll appreciate how well you've done the model and the work that has gone into it (need to be a model builder for that!) but I am sure they will enjoy having the model. Are you planning to do their licence plates as well for the finishing touch?
Nice to see a member has helped you out - not suprised to see who it is, Geoff is one of those guys who are a credit to our hobby.
Tim - I am honoured that you like my model, I like your work and articles very much indeed. Regarding the engine, I often think about how I would like a 1:1 street rod to be and a dual carb small block Ford engine is a swoopy '40 coupe sounds like a nice car to have in the garage!
