Dura-Coat Questions

[Smoothbore]

I have an older Wingmaster 870 I am thinking of Dura-Coating.

Do you apply the Dura-coat to the entire receiver (outside and inside)
or do you stuff rags inside and just spray the exterior?

Is this process hard to do? One coat, several light coats?

Any info would be appreciated.

It is much the same as any airbrush paint job, prepwork is everything. Several light coats I find works best. try NOT to get much inside though, and do not work in a poorly ventilated area, the fumes are unreal, so is the trip come to think of it
