The only clear coat I use is 'Plastikote' clear matt acrylic but you can also get satin and gloss finish. You can get it in Hobby Craft, B&Q, Wilcos... pretty much anywhere to be honest. It goes relatively far and gives a really tough finish. It is also really forgiving if you accidentally put too much on. It doesn't run badly so you won't end up in a drippy mess. 'Krylon' and 'Rustolium' also do some very good acrylic clear coats but they tend to be a lot more expensive and can be tricky to find.

I find that your primer layer is more important than a clear coat for preserving your paintwork. Getting the primer right aids adhesion of the other paint

There are a few guides over on the Britnerf forum if you want to look in to more of the paints and modding materials available in the UK. Like everything, it's finding a combination of paints that work best for you so I can only give advice based on my own experience.

Here in the UK, you need the blaster to be at least 50% brightly coloured for it to comply with the law. This doesn't mean that you have to leave part of your Rayven that awful lurid green, but you do have to choose another bright colour. If you fancy a read, we have done a fair bit of research on this over on the BritNerf forums. Lots of words.

As for your blaster, it's a fairly difficult genre to theme a blaster on since it mainly focuses on weird beasties and the like.

Hellboy had some Lovecraftian elements to it so maybe incorporating some of the films steampunk/dieselpunk ideas into your blaster will work well with your costume.

Looks to me like a Tamiya connector.

Airsoft batteries (or pretty much any LiPo/LiFePo battery uses either a Tamiya or Deans connector. This definitely isn't a Deans.

Either way, you should be able to get hold of one from any good electronics/RC model store. Failing that, look for 'Tamiya Connector' on eBay. The battery will be fitted with a female connector so you will want the male (plug) to attach to your blaster.

B&Q and Hobby Craft both stock a good variety of spray paints but I don't think they stock this perticular type.

You can create a similar effect using a high gloss basecoat and a metalic 'glitter' spray. Failing that, go to Halfords and have a look at the different colours of metallic car paint. There are usually some pretty bright 'candy' colours there.

This is really neat man, I have one question though, does the stock feel wobbly at all after you shaved down those gray pieces?
So what you're saying is, you could basically have up to like five different settings for your stock, instead of just two. That's pretty cool.

The grey nubs are merely 'stoppers' preventing you from removing the blue piece so there doesn't seem to be any adverse effects of shaving them off.

Theoretically you could add as many stops as you can cram into the white piece. Be careful not to place them too close together though otherwise you could end up breaking it.

It is also worth mentioning that you have to be careful to get your new holes the same size as the original two. Make them too small and the stock won't lock in position properly. Make them too big and the stock will rattle around.
