darren m Posted November 9, 2014 Author Report Share Posted November 9, 2014 is there nothing really good that can be painted on that would help Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted November 9, 2014 Report Share Posted November 9, 2014 depends really, can you remove the surface rust easily enough on all sides? I've done a few repairs over the years with varying levels of success, hammerite rust cure works if you can cover all the rust, so not good on boxed sections like sills, also try a zinc phosphate paint which worked really well on blistered paint bubbles, still had to grind out the loose stuff first though and then respray.

88b Posted November 9, 2014 Report Share Posted November 9, 2014 If it's close to a suspension or seat belt mount it would be an mot failure, something else to think about. Quote Link to comment Share on other sites More sharing options...
ferguson_tom Posted November 10, 2014 Report Share Posted November 10, 2014 Dont bother with any of the oxides they are **** paint nowadays, get a wirewheel on an angle grinder and clean area up as best you can splash a bit of jenolite on and then cover with a decent paint like a Zinc Phosphate primer.

Luckyshot Posted November 10, 2014 Report Share Posted November 10, 2014 (edited) Dont bother with any of the oxides they are **** paint nowadays, get a wirewheel on an angle grinder and clean area up as best you can splash a bit of jenolite on and then cover with a decent paint like a Zinc Phosphate primer. And it will still come back through, either cut it out completely or just bodge over it every other month. I know what I would do.

andypaint Posted November 10, 2014 Report Share Posted November 10, 2014 Grind clean then put some vactan rust killer on. Weld in new patch. thenew lechler epoxy primer. Then can be over painted It's what we do in bodyshop but make sure you also treat the rear of the repair. Quote Link to comment Share on other sites More sharing options...

Biffo Posted December 6, 2014 Report Share Posted December 6, 2014 Over the years I had "classics" (rusty piles of ****), I tried lots of converters and oxides - none of them are a permanent repair, as said above (cut and weld for that) but I got the best (longest lasting) results using products by Bilt Hamber. From memory there's a solution you make up that you can soak smaller parts in and the rust is broken down and removed (not converted). I think it was also available as a paint on/wash off gel for panels, and they do a paint on converter as well. I've not mucked about with rusty stuff for a while so don't even know if any of this is still available (usually, if something is any good the EU ban it !). It definitely wasn't cheap, I remember that ! Quote Link to comment Share on other sites More sharing options...
four-wheel-drive Posted December 6, 2014 Report Share Posted December 6, 2014 I think it all depends on how much the car/truck is worth do you plan on keeping it for long if its a quick fix on a cheep car/truck paint the rust with some rust inhibitor and cover it with some gaffer tape will not look good but it will keep the water out until you ether get another car/truck or can afford to have the rust cut out and new metal welded in fillers only tend to last a few months.

spandit Posted December 7, 2014 Report Share Posted December 7, 2014 I like the Flag rust converter paint but you need to cover it with something else like Waxoyl once it's dry Quote Link to comment Share on other sites More sharing options...

andypaint Posted December 14, 2014 Report Share Posted December 14, 2014 POR 15 paint . http://absolutecoatings.com/POR15-Brand.php It is fantastic stuff and works well and stops rust for good. But the prep is hard and needs to be applied properly or its just a waste of money. Can't see some one stripping every square mm of underneath of car to apply por15.
