Chassis protetection - wax based

[alexcurtis]

Afternoon

I have been doing a few bits and pieces under the car recently and noticed that while the chassis is solid (apart form one hole – that is for a different post) but really needs a coat of some sort of chassis protection, as there is a lot of surface rust. It has previously had a coat of what I assume is waxoyl on the chassis and as I am not prepared to take the body off to take all of it off I am down the route of a wax based protection system.

It seems that Dinitrol then seems to be the best product out there? is this still true?

This thread which is now 2 years old recommends using Dinitrol and in particular 3125 and 4195 (second to last post)

from the rust website though they actually recommend using FE -123 as well which sounds sensible though the kit comes in at £125…

Second question is for a Griffith roughly how much will I need of each product? As they are sold in 5L pots or I can buy in 2x1L of 3125 and 3x1L of 4195 for £89 aerosols.

Thanks all

I have used Finnegans waxoil. Get at least 2 litres. 1 litre will do exposed chassis bits underneath. Wire brush off any loose powder coat and treat with an antirust paint. Coat with Hammerite paint then waxoil.

Treated my Griff outriggers as follows. (Without body off) Clean off all flaky paint dirt etc from underside and treat as described.

The unseen upper surface of the outriggers can be cleaned at best!, by threading a strong 1 inch strip of course grade emery over the top of the tubes and vigoursly pull both ends with both hands to loosen and remove any flaky paint rust, dirt etc. This procedure can be repeated with a strip of cloth soaked in waxoil. A messy job. A curved wire lead can help to thread the emery and the cloth over the tube.
On the Griff inside the front and rear wheel arch just above the long side outer outrigger tube, there is a finger hole. This can be used to thread with some wiggeling and patience, a 5mm plastic tube with a coarce spray head, through from the back to emerge into the front wheel arch.
There are a number of kits that supply this with a hand pump for pumping the waxoil. Whilst pumping, slowly withdraw the plastic tube soaking the outrigger tube in the process. Lots of newspaper on the floor to catch the excess waxoil. I used waxoil diluted 50% with white spirit. Its easier for spraying and kreeps further into the rusty bits.
The finger hole as described is where a lot of water and dirt thrown up by the wheels gets in to start the rusting. This can be effectively prevented by blanking off this area with a shaped flap of old mud flap etc secured in place with silicon. Good luck, its a messy job requiring a lot of patience.

bump to the top,

has anyone had any experience of dinitrol over waxoyl? or anything else dinitrol sound expensive but if it is 2-3 times better then worth the money as it will be a long painful job as i read it!

thanks
