Frame Rustproofing

Hi all,

I'm thinking of rustproofing the frame inside on my BJ8. Apparently Dynax s50 has had good reviews, comes in an arosol can, and a 2 ft long tube to get into all the nooks and cranies.

The problem is I can't find anyone in the states who sells it. And I hear they won't ship to the states as arosol cans can't fly?

Anyone know where to purchase??

thanks,

Jerry,

As an alternative, you may want to consider some of the DIY coatings used by a number of LBC owners.

A good friend who had a number of LBCs responded to my query of what he used to rustproof his frames. Being a very experienced and practical guy, he responded that he mixed equal parts of coal tar and kerosene, sealed all holes in the bottom of the frame and drilled new holes in the top of each frame section where they hadn’t already existed. He then would fill the frame with his concoction and, after plugging the fill holes, he would drive the car around the block a few times each day for at least 3 days before draining the mix. He felt this concoction would seep into every area of the inner frame, displace the moisture, and seal everything with a coating of soft flexible tar once the coal oil evaporated. Although this proved to be a very effective treatment from his experiences, the smell of the coal-oil/tar mix seemed to linger for almost a year.

Just a thought,

For what it's worth, this is what I did on my BJ8. While doing frame repairs I had the front of the frame rails open to replace the sway bar mounting plate. I bought the smallest chimney sweep (like a round wire brush) that I could find and trimmed it to just barely fit into the frame rail. I then used that ti dislodge any loose rust inside and vacuumed it out using a long piece of sump pump hose as an extension.

Next I picked up a soft bristle toilet cleaning brush and trimmed that to just fit into the frame rail, dipped it in POR-15 and stuffed it up and down the length of the rail until it was dripping out of the drain holes.

Cheers,
Chris

Eastwood sells an internal frame coating with a long hose for application that I used. Ask me in 15 years if it worked. :wink:
 
Richberman,

I saw they offer two types, one is a rust encaptulation, and one a wax similar to Dynax, which did you purchase?

I bought an undercoating wand from JC Whitney and used it to fog LPS3 into the chassis. Seemed to work pretty well (a quart or so of the LPS3 went somewhere).

On some (older) tube-and-fabric aircraft linseed oil was used to prevent rust inside the airframe tubing.
