I use the Decal Works application kit.
15$ but well worth it.
I only pull half the backing off initially so I can screw it up too much.
Both shroud and graphic are soaked!
Use a small plastic putty knife thing with cloth wrapped around end to squeegy out application fluid.
Be careful if you using an industrial heat gun (I know)
Shouds aren't too bad, Rear panels are more difficult.
