Flame treatment or heat gun?

Will a Hot air gun provide the same results (Not a Hair Drier) It gets hot enough, was wondering if part of the treatment was a burn off or CO diffusion.

    Don't remember the temp they need to get too, but it has to be a VERY high heat gun.

    It would need to get very hot and heat a specific spot very quickly. You want instant heat while moving to prevent melting of the plastic.

    I'd stick with flame, but if it's a smaller part, you could use a heat gun, but as @NotSoFast says, be careful

    Kind of from the sound of it there is some CO chemical reaction, Its a little trick that I had learned in doing clears and epoxy finishes in wood working, Carbon Monoxide molecules are some sticky buggers and will attach to other gasses. When you are doing thick glass coats or embedding finishes you use a torch with fast passes to pull bubbles out.

    The flame treatment we have in our training booklet was written by 3M and I would have to say that if an electric heat gun would work instead? I am POSITIVE that 3M would have put that in the outline instead of a propane flame torch...

    Just saying...

    Nope heat won't do it it needs the plasma of the flame for the chemical reaction. 3m has a write up on the process but I cannot find it.
