I've blued about 15 guns now and have an occasional problem come up. I get some brownish/ red stains in random places after 4 or 5 applications sometimes. Nothing major, but as I finish more coats, the random spots do not turn to a black, nor a gray, they just stay brownish red. They eventually turn and look o.k., but if the light hits the steel just right, you can see it. It's just a blemish, but you can see it if you look close.
It's rust of some sort that doesn't turn when I boil the part. I'm using Pilkington's slow rust solution, and I'm boiling in well water. I'm NOT changing the water between coats, I'll keep the same water in the tank for 5 or 6 coats...usually until the gun is done. Is my water getting contaminated?
I'm doing a Browning BPS right now and the receiver turned up with a couple areas that are "stuck" on brown, but the rest of the receiver is coming along fine.
Any thoughts? Thanks.
