I knew when this started that it would come to this. Use of words like "hobbyist" and "properly" and "any imaginable" show a deep seated bias against thinking "out of the box".
You don't know how wrong you are.
I'm an engineer, a hobbyist and a tinkerer. I actually enjoy hearing about how people have come up with ingenious ways to solve problems with unorthodox solutions.
I don't have any problem with people using expedient finishes on guns either to save money/time or because it suits their particular application better than other finishes available. That's not an issue at all as far as I'm concerned.
What I don't agree with is saying that typical gun-cleaning solvents will damage gun finishes. They don't. They may damage finishes that aren't typically thought of as gun finishes but that's another story entirely.
I was primarily responding to the comment: "Solvents are not needed with modern ammo and can damage the finish on a gun or on the wood."
That makes it sound like we all risk damaging the finish on our guns every time we clean them with typical gun-cleaning solvents which isn't really the case.
someone has applied some sort of aftermarket finish to a gun, a finish not typically used on factory firearms and one that's not commonly used to refinish firearms, then it is certainly true that gun-cleaning solvents might damage such a finish since there's no way to know what finish might have been applied or what solvents it is compatible with.
