So mustamg engine bays are typically fully painted right? They are also painted in a paint that can typically withstand solvents right?
I did an acetone wipe of the firewall and found the black paint easily came off without much effort.
Bottom left, you'll see some black paint that remains, as well as into the trans tunnel. That's the POR I spread about 15 years ago. Glad to see it doesn't come off easiy. I may actyally add some more POR-15 in that lower area while i'm here.
But, it's interesting to see that below the firewall seam, the black paint came off easily and down to the E_coat. Above the seam, it remains. Wasnt the only spot i was able to wipe the black paint off. Rad support and aprons also had paint wipe off, although not as much. I couldn't go crazy though as i obviously needed to stay away from the body filler. I found out the hard way that acetone softens that right up. Oops. ALl fixed now.
On the plus side, i'm pleasantly surprised to see all the other sheet metal is in really good shape. Well..other than the frame rails. But no rust around the cowl and base of windshield as well which was a relief.
With all these fumes and solvents and paints, i ended up buying a supply air respirator. Pump goes outside in the fresh air, and then a 20-25'hose feeds fresh air to my mask. The smells of the filler and acetone give me headaches. When i'm done, i'll sell the respirator off.
