DEFINATELY! I cant reccomend liquid mask enough, its a lot easier to put on than maskin tape although it takes a bit longer (so it can dry) but its so much easier to work with.
If you can afford it go for the bob dively stuff, its available from JE spares or from ebay in america. Do a search on here for it and you'll see why everyone raves about it!
Oh and as for the shell, it looks pretty good - its always a good idea to start simple! And dont forget, if the paint job doesnt come out that well then just cover it with stickers!
