If you are going to use an heat gun and this is you first project then aviod using a hair dryer (you have no real temperature control) use only a decdicated covering heat gun. Then learn to use the air bleed valve on the heat gun. Most folks get the heat gun entirely too hot and fail to open the bleed valve to establish an appropriate temperature.

If this is you first covering job I normally recommend using only an iron (a real sealing iron not a household iron) Initially using the iron only technique is far easier for most folks. And remember folks always want their first one to be perfect, well ain't gonna happen (there are new skills to be learned achevable only by doing) but be assured they will get better and easier each time!

For the Record I now only use Monocoat having used most everytype avaliable since the advent of film coverings.
