I may be wrong, but I thought a galvanizing spray needed to work on a cleaned metal surface - inside a chassis section, it'd be sprayed onto dirt/rust/paint etc., but if it's free it may be better than nothing!

Hi all.
Just bought a great conditon 06 d40. Chassis doesnt look all that bad and hssbeen undersealed at some point. Shes out of the 12 year warranty , shes a keeper, love the truck, time to treat the chassis best i can. I plan on jenoliting as much of it as i can and pump it inside the rails. Then undersealing with possibly raptor or a good quality equivalent. I run a small fab / machine/ metalwork shop, got all the kit and have access to a ramp when it comes to undersealing.
Im thinking yes but you guys are the experts, is it worth adding the strengthening plates before i underseal ? For me its pretty easy as im a fabricator.
Just nice to hear from people who have been in the same boat. Chassis is not cracked no were and looks pretty good but i am aware its an internal thing.
Cheers in advance.

Good thinking, many say that Dinitrol is a better product to keep corrosion at bay.

I've got some strengthening plates in my garage... My concern about fitting them is that they could create a rust issue between the plates and the chassis.

Yes i did notice dinitrol pop up. I will look into that.
Yes , i suppose rust could build up behind the plate. Its a tough one.... wait for.the chaissis to crack then repair or beef it up before it does and see how it fairs in the years to come.
Guess you have re done your chassis ?

Do you know of the kitchen baking foil trick. An easy way to mask off the bits that don't need gunk spraying on (exhaust, brakes)

Heh that's a great idea. No ive never thought of that. Good shout. I will do that. I usually just use pairs of old overalls when im welding so would of just done something like that but the foil trick sounds perfect. Thanks for that.

Dinitrol kit and strengthening plates have turned up. Think im gonna weld the plates on over the next few weeks but leave the undersealing until middle of summer when everythings is nice and dry. Dont wanna be locking any moisture in really.
Thoughts ?
