Chassis paint or underseal?

Now I've got the defender (and intend to keep it for many years) I am going to treat the chassis. It's 1yr old and to be honest looks brand new with no rust etc at al,l I am putting this down to luck as opposed to improved land rover build quality!!

So is it best to paint or underseal with waxoyl / dinitroyl. I was thinking of painting in POR15 and then dinitroyl the insides of the chassis as per previous threads, thoughts anyone?

Cheers Darren

Darren,

Ether do a search using 'Dinitrol,' look up posts by Zagato, or 'PM' Zagato he is the veritable oracle on this subject and there's loads and loads of posts and good advice on the issue...

Using the search facility and just by putting in 'Dinitrol' as the subject and Zagato as the author throws up 38 threads. If you go through life with your head in the sand....all people will see is an ar5e!!

Treat every day as if it is your last....one day you will be right!!

Cheers for that, will do. I used POR15 on the discovery battery clamp a few years ago and it's still as new where as when I did it in Hammerite it lasted a few months in comparison.

As you know then there are a lot of lanes around here

and the mud tends to stick quite well! The defender is in for a few warranty items at the minute, the courtesy freelander was used immediately down the lanes for a try out!!

I used to have (well still have and about to sell) a red disco, lifted with winch bumper etc that I've been trundling around Rushden in for 10yrs, you may of noticed it / me Darren

DarrenJ, as K9F says there's lots of threads and Zag is the dinitrol "oracle".

chassis seem to rot from the inside out, my 90's chassis had silty mud inside the chassis, takes a while to wash it all out and a few days to dry.

before you treat the insides of your chassis make sure it's clean and dry .. if there are a few owners nearby, why not consider investing in a USB endoscope, you could then inspect the insides of the chassis.

I have used dinitrol / waxoyl and a 3M product in different areas on my truck.

Good luck with the treatment and post up some photos

OED meaning of oracle "an authority which is always correct" Hmm...that would be nice wouldn't it, instead of grubbing around under Land Rovers I could be a world power and my first ruling would be to have two types of car only, Defenders of course and Prius

Darren to paint your chassis in POR-15 is going to an extreme as BPman says they tend to rot from the inside out, but you will never need to do the outside again and it will always looks great, just remember not to paint over anything you may want to undo, axle casing nuts, sump nuts etc and any threads cos once it's on it won't come off again

It's a longer job than you think, you end up painting everything you possibly can but It's VERY satisfying

p.s. Don't forget their are two types, use the UV resistant stuff for any areas that will be exposed to sunlight. I used the ordinary on all mine but for the outer side of the rear cross-member and it has been fine and it spends quite a lot of time in the sun

It's not that big an investment:

I have not done the inside of the doors and bulkhead yet. After this summers trip I plan to buy a new injection gun (the old aplicater gun is not a very good one) and do it in September time. You are will come to come round and do your at the same time. I agree totaly with what others have said about it being very important to do the inside of the chassis. about eighteen years ago I had a lightweight and the chassis was really good on the outside (because of the military underseal) but it rotted from the inside out.

I have always undersealed my land rover myself but it is a very dirty job and every time I do it I swear that next time I will pay someone to do it but that never happens

I have recently done my chassis with this stuff and I must say for the price it seems very good. Goes on very easily and really seems to protect well. Looks very good too.

I painted mine and put duct tape over the side holes in the chassis to stop water and crap getting into the chassis, 1982 88" 2.25 diesel

I bought a mixed selection of rubber bungs (in fact the shops whole mixed selection box - he wasn't happy

but that's what they are there for to be sold

) and have managed to plug most of them. Think I left the bottoms ones to let water drain out.

Nice idea. The hardest one to "bung" will be where the cable enters the chassis on the starboard side, aft of the rear wheel and about where the mudflap bracket joins the chassis. Think you will find that the duct tape will be your only man for the job here.
Hope you appreciate the use of the nautical terms,Zag. 1982 88" 2.25 diesel

Let me know when you're doing the bulkhead etc and we could maybe combine, I have a compressor too if needed. Darren
