If you want it to be very easy, buy an ARF.
Covering is not altogether simple. When I use film, I use Monocote I have had great results witht this product.
Others will swear by Ultracote ect, I cant speak from experience in regard to other films because Monocote was the first film I tried and I was satisfied with it, so, its all I use when I cover with film.
Get yourself an iron and heatgun and a LOT of some kind of blades and go for it. Your 1st job wont be perfect, it doesnt matter, youll soon be on to other planes and you will learn a great deal from your 1st experience, just follow the instructions that come with the covering, youll do fine.
