I just ordered some replacement patches for the bottom of my passenger door and the bottom of my rear ambulance doors, and I was thinking about pouring Eastwood’s rust encapsulater down in the panels once I got them welded up. Pour it in and slowly rotate the door around as to coat everything down in there. I have repaired a small bit off rust on the upper side panels as well and was thinking of doing the same to them. I first thought of doing it with POR15, but a buddy of mine said not to because where it can leak out on the bottom of the doors and any of the seams on the side panels. Do you think the Eastwood’s product will work or does anyone have any better ideas?
