JD 4700 Curtis Cab rehab

[tlj87]

I made a deposit on a 2000 John Deere 4700, Power Reverser, 4x4, 400X loader, Curtis hard-sided cab. The tractor is about 7 hours away and I will be traveling to do a final inspection and if OK, purchase and bring it home next Saturday. The tractor has 608 hours on it and appears to be in very good condition. The only known issue is the peeling paint/rust on the cab. The dealer sent some close-up photos of this. The dealer stated that there are no holes, the metal is solid. I am wondering what the best approach is for repairing this. I'm thinking it would be best to remove the rubber gaskets and glass, but I'm not sure how feasible that is (in terms of being able to reuse the gaskets or availability or cost of replacements). In terms of equipment, I have an angle grinder with wire wheel, various electric sanders, and pneumatic needle scaler. What are the best products to use? Should I use a product like POR15 or should I wire wheel the rust off and just use a regular primer then paint? Should I use OEM JD paint or would another brand of matching color be as or more desirable? Thank you.

To get a proper rust removal the windows must out, looks like you should be able to reuse the rubber list with no problem.

I hope for your sake that it's not Powder Coat.

If it is, what does that change about the situation?

EVERYTHING! Unfortunately. Sometimes you can't stop the scab from coming off, and often you can't get coating you want to come off. I had lots of stuff sand blasted and powder coat is the worst to get off. Often the blast medium just bounces off the surface, even thought the surface isn't even adhered to the metal anymore.

look here, note that you can use the string trick to remove the glass without cutting the rubber if it's still pliable.. Know How Notes: How to Remove and Install Flat Glass WindowsNAPA Know How Blog

If powder coat is loose a putty knife will peel it off good where it's still tightly bonded just feather the edge and rough up the powder coat and paint over it.
It may not be a concours car show paint job but it will protect the surface and look good at 10 feet.
And it will look great from the inside during a cold snow or rain storm.

How can you tell if it is powder coat? I just purchased a 4310 with a curtis cab, same issue.
