I don't think you will get a finish as good as powder coating (but it depends how good it's applied I guess) It's generally hard wearing and looks professional.
But saying that I dont know what constitutes badly applied and properly applied coating process.
The price from Marlin may seem expensive but they might do a v.v. good job.....but then again
not really helped have I.
I'll get me coat.
