FE-FC Holden Discussion Forum

Hi all, wondering what is recommended for underbody surfaces. What are people using. My fc is pretty much rust free with just one old repair on the passenger side for and a replacement wheel well. Ive pressure washed underneath and am now working on getting all the hidden dirt and grease out of the nooks and crannys. A bit of wire brush work and then gonna hit it with something to make it look awesome and protect it. My preference is por15. Has anyone used this or is there something better/easier to use?
Cheers Rick

I've used Steinschlag. It's a rubberised stone guard type of coating.

 
A bit of talcum powder every now and then works for me

Por 15 is good as well

Zulu I think you have mixed up your forums. A mind, body and spirit hippy forum is the one your looking for. Although maybe it would work if I had fat tyres/legs as it would stop rubbing/chaffing? Or maybe your are a sales rep for Johnson and Johnson? Ha ha! Not sure that por15 would be any good for my own underbody? Might have a few issues with that?
Cheers Rick

I used POR15.  It came up very well.  You have to give it a very good clean and a bit of a bugger if you haven't got a hoist.  Lying on a roller board with the vehicle on high stands was "a ton of fun" not.

ther is an Aussie made product called KPH, same as POR15 and a bit cheaper. Have'nt used it yet but have been told it is just as good, others on the forum have used it and it looks ok. They also do a fuel tank repair kit that has also been used by a couple on the forum as well.

KBS coatings

I was only doing spot repairs and I put some KBS over the repairs, then I used some cheap underbody waxy, bitumen stuff by Septone to make it look OEM with surprisingly good results.

it looks good, it stays flexible, but I got covered in it...

I had given thought to use UPOL Raptor ute liner, but I think the cheap flexible stuff may be better for underbodies.

Cheers

Love it Gary ...

Hey, I've been experimenting with some bituminous coatings and the septone stuff was great off the gun. It's like halfway btw Ute liner and thin chassis black.

I'm looking at using Septone Chassis Black under my ute - taking the opportunity atm while the front end is off to get inside the wheel wells as well.

Not sure about prep for it - i'm cleaning wire brushing and rust converting, but is a primer needed under Chassis Black or does it go straight on?

TIA

I'm no expert but i would think that you would need a primer.

No expert either but have heard bad things about bituminous coatings forming rust underneath. Get it clean as possible, light coat of etch prime. That will give the rest something to stick to.

I used a product called POR.  It is a good rust preventative as well as giving an very smooth finish and easy to paint on.  Make sure you use gloves because if you get on your skin it takes about a week to get off.

I've had good experiences with KBS coatings.

POR15 or KBS first, then a bodyguard product if you want further protection and a bit more noise damping.

Thanks for the responses everyone
