Try the Napier stuff (VP90?), it helps if you dry the gun thoroughly and gently warm it before putting it awayWhent to get the rifle out of the cabinet earlier on this afternoon and there was rust formed on the lenght of the barrell.
I wiped it down with an oily rag and it dissapered. Is this caused by condensation? And are there any products on the market to stop this.
+1 lived in a caravan on the shoot for 3 seasons along with my guns brrrr sure vp 90 s helped keep stuff rust freeAs per above leave any guns to dry out before putting them away. I wipe mine down with an ever so slightly oily rag and the barrel is swabbed with an oily patch.
The VP90 patches are very good, I was amazed with the results. They are different from silica crystal type desecants that pull moisture from the air, the VP90 releases an agent that is attacted to metal and guards against corrosion. Pricey but worth every single penny. Ali
