white90 Posted June 26, 2007 Share Posted June 26, 2007 Whilst removing the rear winch I found some scabby rust on the inside of the x member ends where the jacking tubes come through it. a good bashing with a screwdriver has shown the metal to still be sturdy, I've removed the paints and loose material, I have a choice of coatings to put on the bare metal(rusty) suggestions as to the preferred choice?

ciderman Posted June 26, 2007 Share Posted June 26, 2007 How about using them all in the same order ? Quote Link to comment Share on other sites More sharing options...
white90 Posted June 26, 2007 Author Share Posted June 26, 2007 Sounds like a good idea I'll use the lot Quote Link to comment Share on other sites More sharing options...
ThreeSheds Posted June 27, 2007 Share Posted June 27, 2007 Sounds like a good ideaI'll use the lot I can imagine 'Time Team 3000' trying to work out what it was without a clue from the context because there will be nothing else left...

Fatboy Posted June 27, 2007 Share Posted June 27, 2007 Tony, Be careful with the Zinc Rich stuff... Some of these primers with strong solvents are designed to go on bare metal only. I made the foolish / naive mistake of painting the entire chassis with Zinc rich primer and it reacted with the original coatings that were still on there. Unfortunately, it was not a typical blistering, more of a toasting where it slowly became brittle and lifted, so there was no obvious signs until a few days later when it started to fall off in sheets... I went to Withams in Lowestoft who make the stuff and the Lab Tech told me it was due to the solvent being stronger than the solvent in the original paint... I'd recommend doing a test piece first and leave it a couple of days. Quote Link to comment Share on other sites More sharing options...
gazelle Posted June 27, 2007 Share Posted June 27, 2007 What is the recommended prep for each of these then? Martin Quote Link to comment Share on other sites More sharing options...
02GF74 Posted June 27, 2007 Share Posted June 27, 2007 POR 15 is supposed to be good on rusty metal. don;t use it on new metal since it will not key - needs theroughness/.rust - and flake off. Quote Link to comment Share on other sites More sharing options...
white90 Posted June 27, 2007 Author Share Posted June 27, 2007 Cheers but I tried POS15 and it was carp and is still falling off as I type maybe I applied it wrong. rusty/good/painted it is falling off the lot Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 27, 2007 Share Posted June 27, 2007 Galvafroid or Zinc 182 should go on bare metal, then paint on top of it. Les. Quote Link to comment Share on other sites More sharing options...
BLACK CAB Posted June 27, 2007 Share Posted June 27, 2007 I have used Zinc 182 on stable but heavily rusted parts, it lasted very well - just top coated straight over it. As previously stated only really for use on bear/rusty surfaces. Quote Link to comment Share on other sites More sharing options...
