Galvanizing frame (2 Viewers)

[wpns4l]

Quick question for those that have galvanized their frames. I dropped mine off the other day to get galvanized and they just called to give me a warning basically.

They are saying because their is so many pieces or parts of the frame that are flat metal riveted to other flat metal that basically the acid solution gets trapped in between the riveted pieces and then when it gets galvanized it turns to salt crystals which will draw moisture in and then causes corrosion from the inside out.

For those that have done this did you ever have issues down the road? Did they give you the same warning? I live in socal so not really a salt/wet environment so maybe not an issue?

To clarify the second paragraph they are claiming it's a possibility not that it's 100% going to happen.

Interesting. Pickling acid is a "salt solution" so to speak. Maybe they need to soak the frame in the rinse solution a little longer and perhaps pressure wash the joints in the rivet area. Hot dipped galvanizing shouldn't be adding any salt. Phosphating/chromating treatments are salts. So is the hot blue on nice guns. We washed them in hot water, then soaked them in oil, wrapped in several layers of news paper for a few weeks to "cure" then put them back together.

Browning had issues with walnut logs that were submerged in sea water for long term storage. Later they dried the wood and made stock. After some time the salt in the wood ate into the guns medal where it touched.

I'm back home now and after reading a bunch of threads here and even looking on the land rover forums I can't find where this has happened to anyone.

Not saying the guy who does it for a living is wrong but I feel like if this was a major issue I would be able to find people complaining about it.

I think I'm gonna call them back and tell them to proceed.

I watched this a few weeks back. It's not a land cruiser frame, but still cool process to see.

There's a few other videos on his channel where he preps the frame if you want to check that out.

No any kind of problems here.

Most hot dip places are afraid of auto frames for some reason.
I have one near me, that we use regularly, they flat out told me they will not dip frames.
The excuse given, was that the heat will stress relieve the frame and it will most likely twist....I called bull****, but they still refused.

have done a few
1. Put ALL bolts in the frame prior to dipping. If not they will fill up and you will hate life with a tap in your hand
2. Do ALL welding prior. Attempting to weld galvanized is a nightmare.
Nothing will happen to your frame. It’s a hot dip like all utility Company metal.
Make sure those clowns don’t drop your frame and bend the back bumper

I used high temperature silicone to the bolt holes. Worked quite nicely, needed only a little tapping. Bolts can seize badly if the thread is too long though.

No problems with mine at all. I even galvanized my tub.

I got the frame galvanized. So follow up question for those of you who did it. What did you do for paint? All the LR forums talk about T wash which inst sold in the US. I've heard some people just use vinegar and degreaser followed by etching primer. Some say use epoxy primer. Some use other acids/metal prep.

What did you guys do?

 

[macdaddy59]

I sanded with 220 grit then applied a metal etching primer than chassis paint

350 for the galvanizing 400 to get old paint blasted off before hand

 

[newmexicokid]

Seems way worth it.

very worth it

I used phosphoric acid, just a little while (it starts to react/makes foam), then washed it and painted with black epoxy. It’s looked nice since (almost 6 years now).

There was rough zink surface in some areas which will be seen, so I used aluminum bondo to them after grinding. It’s held nice too.
