Treating Rust

[Leeds Sprint]

Hello<br>
<br>
A friend of mine at work has asked for some advice on dealing with a small amount of rust on the sills of her Renault 5. She says she has heard of a product that you can spray to neutralises surface rust and seals the area ready for paint? <br>
<br>
She wants to know what this product is called and where you can buy it. Any suggestions?<br>
<br>

I'll make sure I tell here that.<br>
<br>
No really, what's the spray called? I know I've heard it mentioned before.<br>

There are a few products available which all claim to treat rust and prepare the area ready for painting. Kurust is one than springs to mind, but I can't think of the names of any others. I seem to recall that Practical Classics did a test on some of these some time ago (erm, a long time ago actually) but I can't remember which one they liked the most. I have a feeling that the general view about these kind of products is that none of them are long term fixes...<br>

Best thing to do is to stab the rusty bit with a screwdriver. If the screwdriver goes through the sill, it is most likely rusted throughout, and will need welding. If the screwdriver does not got through the rust, sand the spot, and an area roughly an inch around the spot, to see whether there is good metal underneath. If there is good metal, it can then be primed and repainted.

Thanks for that guys. <br>
<br>
She has confirmed that the rust is not the type that you can put a scewdriver through. That was my first question too. <br>
<br>
This Renault 5 she bought came with a years MOT and only cost her £300. She hopes that if she can treat the rust now that it will make it through next year's MOT as well.<br>
<br>
I have warned her that if she is serious about getting rid of the rust, then she needs to consider having someone do some grinding and welding. I suspect that she has decided that the car is not worth doing all that. Thankfully it's not a Dolomite, because I reckon she will be the final owner before the Renault goes to car heaven.<br>
<br>
My appoligies for posting a slightly off topic post here.<br>

Chris,<br>
<br>
Even if it looks like a surface scab, it's worth taking a really close look and poking it just in case. There's no point taking risks with something that important, even on a cheap old car.<br>
<br>
-edit- <br>
<br>
That said, if there's a small localised hole, a patch would probably suffice to get the car through an MOT, and would be an hour's labour at a garage, or a beer for a friend. A couple of members here are/have been testers, they'll probably give a better answer.

You can get a nice 1850 for £300 ish! Of course you'll have the same rusty sill problem, but at least you won't have to drive a R5.<!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/images/emoticons/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END--> <br>

POR15 do some jollop called Metal Ready that is supposed to kill the rust and coat it ready for the POR15 paint. Seems to work - changes the colour from brown to grey but who knows long term.<br>
To stand a fighting chance you have to coat both sides with paint to seal it. There's no substitute really for doing the job properly and cutting all the rust out.<br>
What is a Renault 5? are they rarer than Marinas?<br>

The most effective product available is called Bilt-Hamber Deox C.<br>
It will litterally eat the rust, leaving a nice, shiny surface. It will need priming however, before you can put a colour coat on.<br>

Bilt Hamber caqme top in the Practical Classics test as I recall. It is dearer than other similar preparations though.

rust killer... lovely. eats rust theoretically, leaving nice usuable surface, but chances are the metal left is about half the thickness its meant to be.<br>
<br>
chop it out n weld it m8 <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/images/emoticons/wink.gif ALT=";)"><!--EZCODE EMOTICON END--> <br>
<br>
then again, renault 5... unless its a turbo or turbo2 i'd get shot of it. the rest of the good metal will be following in the footsteps of the rusty patch very soon.<br>
<br>
tell her to get a toledo. its the way to go...<br>

But the only real way to get rid is cut it out.
