I Highly Recommend This Inside Frame Coating For $20

[Biotex]

I purchased the Eastwood interior frame coating system, and tried it out today. I wasn't really expecting anything earth-shattering, but boy was I surprised!

 

This is inside my frame after powerwashing and blowing out the debris with compressed air. I let it dry for a week after the washing...

 

 

This is after a quick spray down with the Eastwood product: The green is the zinc chromate primer that does wonders for killing rust. It is what is used inside aircraft wings and such. I'm sure many of you know the benefits of zinc chromate primers.

 

Note: The kit comes with a very small hose 24" long that has a conical spray nozzle on the end. There are plenty of holes in the frame to get 100% coverage. One can will do the entire under bed frame area. This system doesn't spray like a conventional spray can. The liquid comes out fast and with a lot of pressure, so you don't want to keep the tip stationary for very long

 

 

 

This is the only part of the frame inside I could take pictures of, but I imagine the rest of the frame looks the same. This is with the rear bumper off and looking forward.

I also POR 15 the outside, but you all have seen that before. I'm sure others have done this before, but I thought it was the best $20 I've spent in a long time.

Nice ill have to try it

I've purchased a lot of stuff from Eastwood. Good stuff and good service.

Zinc chromate kills rust?

 

I know it has been used as a primer for many, many years, but I have NEVER heard that it kills existing rust. Got a link to some documentation on that?

[Biotex]

Ok, I shouldn't have used the term " kill rust". I was refering to the killing rust as in stopping it from happening. The product prevents rust from starting by letting the zinc become the sacraficial metal. Same principle boat engines (transoms?) use with a zinc metal block attached. Hot water heaters have a zinc annode inside for the same reasons.

So a primer or paint with zinc in it will prevent future rust in this way. Any existing corrosion will still be there since you can't undo it, but you are preventing its spread.

 

In my mind it kills it...

 

 

Edit: I looked up the MSDS sheet for it, and it is listed as a zinc phosphate not a chromate. Does the same thing though. Corrosion control...

Well worth the effort IMO.

How big is the can and how many cans to do whole rails?

[Biotex]

How big is the can and how many cans to do whole rails?

 

2 cans would do the entire truck. I used one can for the whole back section under the bed.

• Tough phenolic resin penetrates, converts and encapsulates the rust on the internal surface
  
• Zinc phosphate seals it to prevent future corrosion
  
• 24"-long tube with conical nozzle reaches in to spray coating in a radial pattern for complete coverage
  
• Covers 10 sq. ft. per can
  
• Fully cures in 24 hours

It's called cathodic protection and is also used for protecting underground fuel tank farms; that was the primary reason for it's development. The sacrificial zinc anode rod beds are placed at strategic locations throughout the farm, are charged with rectifiers, and are positively charged with positive DC current flow. The sacrificial anode beds are monitored for deterioration as the current flow increases as the anodes deteriorate. When the current reaches a certain high, the zinc anodes must be replaced to continue corrosion protection for the metallic tanks. Cathodic protection works well on underground tanks and ships/boats because they have highly conductive ground planes, but not so good on vehicles because they do not. Read rubber tires. And because of the low mass of a zinc paint coating, the little protection doesn't last long unless constantly renewed (repainted). However it sure doesn't do any harm, and is a good thing to do, especially in the rust belt.

I read up on this product and plan to use it this summer.. Looks good. I think it will help make the MJ last much longer,

 

Good pics

I agree a ground plane is better when talking about a zinc annode being sacrificial. The word annode implies a negative ground. But what about aircraft? Zinc in primers been used since the 40's and is still the choice primer today for aluminum. No ground plane there. For weight savings, only the primer is used on the inside of wings, fuselages etc... They don't corrode. Yes it's aluminum, but we've all seen aluminum corrode. The key to this is to encapsulate the rust. No moisture getting to the metal goes a long way towards preventing corrosion.

 

For $20 i'll be happy to stick that little straw in all the drainage holes on my frame and pess the button. Even if it is once every couple of years. It would be worth drilling a tiny hole in the rockers, spraying them, then silicone up the hole until the next coating.
