Pug_101 0 Posted May 8, 2006 Hi all, Basically I have a few areas where Rust is getting a hold on my car. So I would like to know what recommendations people have to fix the problem. I am most interested in any proven long term solutions anyone has experience of as I only want to do this once. Thanks Share this post Link to post Share on other sites
boombang 2 Posted May 8, 2006 Only true way to sort it is to cut all the rust out and weld in new metal. Use good quality gas and wire with the welding, and make sure the metal going in is clean too. Get some paint on it straight away, I tend to panel seal bits you aren't going to see (then when its cured spray the appropriate chip guard colour over). Bits you do see, fill with filler, flat back, fill, flat back till almost level, then overfill with a very fine filler and flat back till smooth. Then high build primer, paint, blend into panel and if necessary lacquer. Share this post Link to post Share on other sites

Yes I would agree with you on this for external bodywork or structural areas, but for the bits I have got the above method would be overkill. I should have explained this in my first post. I have some small patches under the bonnet mainly caused by impact damage and scratches done while maintaining the engine over the years. I also noticed when removing the battery the other day the rust has started on the tray there too, due to there being no battery clamp and the battery moving about. I am therefore looking for a acid/paint/sealer type fix as your method would require to much work and expence for such minor amounts of rust. Share this post Link to post Share on other sites
Banjo 1 Posted May 8, 2006 Use a flap wheel in a grinder and grind the rust back to bare metal, prime with acid etch primer and paint normally. Ben Share this post Link to post Share on other sites
mak 0 Posted May 10, 2006 (edited) As said already you really need to get rid of the rust properly...so avoid using any of the 'rust cure' paint on apllications. They generally tend to just cover the surface of the rust and leave a goo (the hammerite stuff anyways). A good zinc primer will help prevent any reoccurence Edited May 10, 2006 by mak Share this post Link to post Share on other sites
Pug_101 0 Posted May 11, 2006 so avoid using any of the 'rust cure' paint on apllications. Yes I do agree about removing the rust and I am doing just that restoring my 73 MGB, but I am interested to know if anyone has had a good experience using the above "rust cure" systems. Maybe one of them works Share this post Link to post Share on other sites
M3Evo 0 Posted May 11, 2006 A good zinc primer will help prevent any reoccurence Couldn't agree more! I painted the brackets for my intercoolers with stuff called Galvafroid. It's quite expensive, but it even protects little uncoated areas (i.e. most of an edge which I somehow missed with the paint brush) I've used some stuff called POR15 rust treatment before. I was bloomin sceptical to start with, but watching rust dissolve infront of your eyes can't be argued with! Share this post Link to post Share on other sites
