Minor Matter - Frost Catalogue - Rust !

[Heapes]

Hi All,

Like me you received a Frost catalogue with this latest edition of MM. I'm interested in some of the rust removal products on pages 7 to 9. They're not cheap. So before I consider parting with my cash, has anyone got any experience with any of these ? Do they work ?

Regards
Steve

It hasn't all disappeared! I've moved all the (unrelated to the question, really) comments that followed to 'off topic', in the hope that Heapes gets some help with the question. For now, just keep T&Cs Item 8 firmly in mind - You agree not to negatively criticise any individual, organisation, product or service...

Steve,

I too am interested in rust prevention and would also be interested in any opinions forum members might have?

I have always been a bit sceptical about magic paints which claim all sorts of rust killing properties but FWIW ..........

The POR-15 anti-rust primer has been around quite a while and I have read lots of positive comments (often from the States)...... From what I understand it has two major drawbacks

1. If exposed to light it will break down and ultimately fail so must be overcoated to protect it

2. It needs an etch primer to allow the top coat to adhere to it properly. This adds to the cost of a fairly pricey product.

There is another product from the USA called "Rust Bullet" which claims better protection and longevity than POR-15 and is also stable in UV light so doesn't need to be overpainted. The test results on www.rustbullet.com do look very convincing.

Both Bullet and POR claim that they work on already rusted steel by bonding the surface into a stable structure which will not flake off and more importantly, will not rust further.

The main drawback I can see with Bullet is that it is again quite pricey and the only UK supplier I have found seem to be "out of stock".

If anyone has tried "Rust Bullet" or any similar product I would be interested to know what you think?

The Dinitrol wax products are widely used and generally accepted as an effective way to at least slow the progress of rusting. They (and Waxoyl) work on the same principle as a greasing or oiling steel. They form a sticky barrier which blocks oxygen and moisture from the surface of the steel and thus impede the rusting process.

Back in the seventies I knew a chap with a Mk2 Cortina who used to put his waste engine oil in his sills - That Cortina had the most immaculate sills I've ever seen .......... but his driveway was a bit of a mess

Again FWIW I have used quite a few of the so called Zinc rich primers and am not really convinced they offer much over any decent coat of paint.

I am interested too. I have heard that jenolite (if that's how it is spealt) is pretty good.

I tried the POR15 paint product a couple of years ago , after stripping the panel in question with nitromors and the excess surface rust taken back with a wire wheel on an angle grinder the panel was treated to a liberal application of jenolite, then the metal ready fluid and then the POR15 applied. Feeling well chuffed with all my effort the panel was placed in a cupboard in the spare bedroom in the dry. Unfortunately when the panel was removed after about six months the dreaded signs of the tinworm had re-appeared in the form of thread - vein like rust appearing under the so-called wonder product. Maybe i was just unlucky but every time now where possible i find there is no substitute for shot/sand blasting and etch-priming.Using a grinder just seems to push the rust deeper into the metal and no amount of fluids,gels and potions do the job they just seem to appeal to all of us restoring our cars on a budget and not having the funds to to get everything blasted. While i understand its not always possible to have everything shot-blasted, try and use new panels and protect them accordingly and for anywhere you can't get access grind off the worst and apply your favourite rust eating potion and i have always used a red oxide or zinc based primer and then depending on your finishing requirements use top coat or a wax based underseal. I am fortunate in having a shot blaster near who does a great job for me in Norfolk although not cheap it does save an awful lot of work and gives me peace of mind as there is nothing worse than spending hours in the garage with the grinder going only to have to get it done by a proffessional after all, not that im speaking from bitter experience of course, NOT MUCH!!! Good luck in your quest to rid of the rust, after all it wouldn't be much of a Moggie without it would it ? Darren
