Protecting the underside of a Disco

Right I'm going to be protecting the underneath of the Disco with either Hammerite, Waxoyl or both.

I would like to prep the frame as best as I can, so going to remove all the mud/dirt with a pressure washer- let it dry and then attack it with a wire brush/grinder..

But while looking for tools on Steel Bay, found a shop that sells grit to be used in a hand blaster, wouldn't this be a lot faster and maybe do a better job?

But what problems do you see with using one, would it be bad if you left some grit where you couldn't get it out.

And firstly would have to wrap all the UJ's and props, brakes etc etc..

i spot blasted my chassie with a £15 grit blast pot from machine mart, you need lots of CFM, But it did a good job on small areas hard to get at with ginder, i then painted with hammerite, then sprayed on waxoyl.
Blow off excess grit with air line, and dont get wax on the air bags.

Sounds good, just spoke to my mate. He says it will be messy as duck. ta very much

Yes it is, but if youre going to do it, do it right and waite for a warm dry day

To right had to many cold wet days working on cars, trikes and bikes for so far. and all the sand can blow away instead of sticking to the floor when it's wet

Do a search on 'waxoyl' dude. not sure you need gritblasters, grinders or hammerite

What about that Por 19. Not waxoil I know but its big in america, vw restoration etc and dries out rock hard and you can paint directly onto rust?

anything that dries rock hard is no good, it tends to crack with flexing then water gets behind

This thread has been done to death, and in terms of sand blasters they tend to blast wiring pipes bushes and every other thing you dunt want blastid to fook, and leave sand in all the bits where you dont want it and fook it to death. If you want to stip it down fine, but a running vehicle no, I have seen it done on two seperate occasions on trucks and it's fokin murder.

It's gona rust to fook anyway if the rust is already there, anything you use is going to cover it and it still continues to rust,sometimes worse.

I tried spraying mine with waxoyl and it rusted to fook under it in a year, last year I sprayed it with a 50/50 hydraulic and waxoyle and it's too fokin wet and cold to check it yet.

If you want to lay under a ****y motor and breath in all sorts of ****, with hours of labour on yer go mucker, most of the bits you aint gona get to anyway. I dont mind scooshing it but fook hours and hours of grief.

If you can get loan of an air needle gun they work good as for the waxoyl try 50/50 with old gear oil and absolutely soak the inside and outside of the chassis and underside of whole motor with it , OK it is gonna drip ALL over the road but if any do-gooders :blah: make comment just ye tell them you are tryin' to recycle the oil by putting it back in the ground .

and it's things like that, that make my fall off my bike.. trucks are the worst for leaking diesel.. Ducking dangerous for us.

It's gona stink forever tho. horrible stuff gear oil.

OK mine did stink for a while but it seems to have lost the pong now after about a month still looks nice and black despite all the salt the council have put on the roads lately pity the rest of it didn't look white with salt gettin' fed up of power washin' every couple of days . :censored:

There's a place down south that does undrside protection on all vehicles by pressure treatment using waxoyl, it would cost about 400 quid for a disco and they do it all in a day. Inside the doors, body work and the chassis inside an out. Might be worth looking at. I put in "underbody protection" in the search and it came up wi theis waxoyl place.

Rustmaster- Home but there are others. There's a gallery of work that been done also.
