I am restoring a 1952 Ford 8N tractor. The stripper does not get all the paint at some locations after a couple of applications. I am assuming this is caused by the large surface profile on the cast iron. Any suggestions?

 

On the pressed steel parts the paint comes off completely.

 

Terry,

What is the temperature of the Cast Iron parts?

How long did you let the KBS Strip soak in to the paint?

Please let me know and I will assist you further.

I live in Houston, Texas. It has been cool but warmer than 55, probably around 60 to 65. The strip was applied on 4 different days to different areas.

The first time I didn't keep it wet other than the first spraying. I was having problems with the spray tip also, my problem. But this weekend I kept the areas wet with the strip product for about 15 minutes and waited another 10 min before beginning to remove it.

It works great on the surfaces that are not cast but on the cast parts it removes about 50% to 60%. A second application gets about 85% to 90% of the color. After drying a power wire brush does not remove any more of the color. It seems to work better on the areas where the casting is smoother.

Cast is very porous. Here are some suggestions.

Get the substrate warmer (70-75).

Keep it wet for 1 hour or more.

Pressure wash off the stripper after it has soaked for an hour or more.

Let me know if those suggestions help.
