just looking for advice on best treatments to protect against rust,products,application and the like.i don't have a compressor or anything like that so has to be from a can unless anyone can recommend a cheap service that will it for me.cheers dave

I use this link for inside the box sections and cavities and like you, I don't have access to a compressor, but the large aerosols have a long tube that sprays in all directions.

Seems to work, everything gets covered in wax!

I did it with dinitrol which worked well

Dinitrol for me as well. I've got a 72 Viva which were notorious rust buckets. You'll never kill rust entirely, but you can slow it down a lot.

The best results I've had so far are using a powerfile with a ceramic belt and a wire cup on an angle grinder to get back to as much clean metal as possible. Then two applications of Dinitrol Converust (18 months later bare metal is still rust free), box sections I use Dinitrol cavity wax - aerosol application using the long tubes they provide - buy off their ebay site as it's cheaper than direct from their own website. On other metal I use Ronseal No Rust - yes it does actually do what it says on the tin. I discovered how good it is when I painted my boat trailers with it 7 years ago and they are still rust free. Before then I had to repaint them every year.

Dinitrol underbody wax in aerosol is also pretty good.

I always use Bilt-Hamber stuff, never tried Dinitrol but by all accounts it is very similar and seems to work just as well.
Not found any other products to be as good

Hydrate 80 is a brush on rust inhibitor/convertor that actually works.
I have a test panel of metal that had pretty good surface rust on, i cleaned a strip across with a flap disc and a strip with a wire bristled brush. Then tried 4 different rust inhibitors down across rusty/ wire brushed/ and clean metal strips.
Then left the metal in my back garden all through a snowy Yorkshire winter and another 2 years.
Its now sat in my workshop and i bring it out to show people who ask why i use Bilt-Hamber (I'll try to remember and take a picture of it)

The Kurust didn't last a month before it was rusting through all over, now you can hardly make it out at all
A friend had Loctite's rust eater, that was showing signs of loosing the battle after a month around anything but the clean steel. After 3 months it was pretty rusty all over and now you can just make it out
I also tried Bilt-Hambers zinc rich primer (as i had some) that did surprisingly well, showing a little around the edges on the rusty strip after a month but holding out mush better than the 2 supposed rust inhibitors above
Finally i tried Hydrate 80 which after 5 years is still there and going strong, there is a slight bit or deterioration around the edges as the rusty panel creeps in under it but considering the weather its been subjected to you can't really complain

So now i always use Hydrate 80 on cleaned metal, 3 layers of that then paint over the top with stonechip covering that on the underbody.

All cavities get sprayed with their Dynax-s50, i use it from an air compressor but they do spray cans with long hoses that i've also used and are very good.
