Windscreen frame.. stopping rust..

[duncanrm]

Hi..

New FJ40 owner..

I'm building up a 1967 FJ40 for family getaways.. As much as I'd like to source all new rust free parts.. money wont permit.. and whilst I can weld, I'm entirely unsure of how this would be approached..

Therefore.. I'm looking for the best way of stopping what rust there is my windscreen frame from progressing too much further.. here's what it looks like now:

I'm planning to hit it with a wirewheel on an angle grinder.. soak in muriatic acid, neutralise, then paint with POR15..

Is there a better approach for stopping what rust there is from progressing further?

With thanks,

With your welding skills i would cut out all the bad stuff and weld in new,who knows it might last another 45 years.

Cut it out and replace with 16 or 18 gauge material.. I'd then spray the inside and back of the new piece with a cold gal material as well.

I wouldn't use muriatic acid. I would use either their metal ready or dilute phosphoric acid. Agree with others that it would be good to weld in new metal.

I wouldn't hesitate to do this if it was a flatish bit of metal, but there's a 90 degree curve with a scallop on the apex of the curve.. not easy to fabricate something like this..

After fixing all the metal. COver all the holes you can and insert old bolts in all the bolt holes. Then pour in some por15, rust bullets or rustolem or anything else you can think of that stops rust. Rotate the frame all around untill the inside is good and coated. and pout our the remaining. While it's drying make sure you move all the bolts around for the winshiel hinges as they have capsure nuts and need to be free when installing the frame back on. Let it dry and then put it back on. You coat the inside and outside and take care of replacing the rust with metal it should last a lifetime.

Bench vise, chisels, clamps, dollies, and some time... you can do it..

For a couple hundred bucks you should be able to find a rust free used one. Look for a mudship to get it to you. It took several months to get a rust free one, but worth the wait.

If you don't have the time or $$ then patching would work well.
