no i got a proper iron for the job. I do have the sock to cover the bottom of the iron , but is it better to cover with or without the sock? Would a hairdryer do the same job as a heat gun? Whats a sealing iron and is it critical? And what is windex and whats it do?

Are there any other main preparations i need to do apart from flling in holes, sanding and removing the dust? Also should i cut the film to a shape which resembles the part i'm covering?
