Question about cleaning out the frame

[Trident72]

I am in the process of preventatively cleaning out the inside of the frame rails. My hope is to coat the inside with Eastwood Internal and the outside with a product such as POR15 or Eastwood Encapsulator. I am using Forum member @Wade How to as a guide. My question is instead of using and working thru 5/8 or 3/4 drilled holes along with the factory dirt inlets, would it be horrible to take a Hole Saw and cut a decent sized hole just to the rear of the belly pan? Use it to access as well as a vacuum point and then when the job is done, simply reweld the plug back into the hole. Thoughts?

The 2000 tj I have been rebuilding had a frame rotting from the inside.I don't know the condition of yours. When I fabricated lower safety caps I put 1" holes at either end. for clean outs . I used eastwood internal coating and there rust encapsulator .Then there frame coating. I cleaned all the rust pieces out first. I know others might not agree with the sizes but they are a beefy frame when new.I have put 1" plastic plugs in and used fluid film to coat it.I just need to remove the plugs to flush it out in the future now.I am sure a smaller hole would work also.

Didn’t you do a pretty intense right up on this? It seems like I remember following a project like this

It was @Wade, good read and he probably could give you some pointers. https://wranglertjforum.com/threads/how-to-clean-your-jeep-wrangler-tj-frame.3249/#post-41576

It was @Wade that I had read .Were he put 5/8" holes I just put 1".He had a really great and in detail write up.It is really important to put some size of drain hole ,flush it well and internally coat it.I will be sure to internally coat with fluid film or Krown every year and not drive it in the winter.Getting rid of rust grows old fast.If I ever replace it it will be with a rust free one.Good luck.This forum is filled with great info and lots of help.

Could you shoot a couple pics? Was it as helpful as I think it will be to have a larger hole to work thru? Thanks for responding

I will do that

Not very clear underneath so these are the channels I made.I also put 1/2" holes between the are were the skid plate bolts go.Nothing is staying in this frame.

Used a 7/8 hole saw on mine right in front of the rear dog legs on the bottom. I then park facing up hill, stick the hose in the front dogleg access hole and turn it on. I then go start drinking a beer. When it's run clean for a few minutes I switch. To the other frame rail. I then finish my beer. I then out the hose in the access hole on top of the rear dog leg and make sure it flushes clear pointing both forward and back. I then do the same in the front dog leg. This process takes about 10 to 15 minutes. I then put a bar sprinkler under the front half of the jeep and go drink beer for another half hour or so. I then move it to the back half and drink more beer. Then I mount the sprinkler between the grill and the winch to clean the rad. After all that I wash the body making sure to flush the torque boxes and rear corners of any crap stuck up there. By this time I've had enough beers that I don't mind so much being covered in muddy water as inevitably I will get back spray on myself. i do however plan to pickup one of those 90* bent pressure washer wands to help clean the under side with.

I coated the inside with the Eastwood internal frame paint and one day may add krown to it as well when I'm sure I have no more frame mods to do. (I suspect welding on a frame filled with oil may get interesting )

So far it seems to be working well as I haven't seen any rust coming out. I think the key is to not spare the water when cleaning.

Can we get your recommendations on brand of beer so that we can stay with original equipment?

Depends on the weather, if it's exceedingly hot then a radler or at least a Corona (lime is mandatory. ) If the weather is just warm the a nice ale hits the spot, I prefer Innis & Gunn. For colder weather a good stout keeps you energized without needing anything like food to keep you going. Guinness, drink it with a knife and fork. (although some some of the dark Russian stouts are good to)
