So what did you do to the tie bars to restore them? Looks pretty nice... |

Eric, I scraped off all the loose rust with an old chisel and the edge of a file. Then used course abrasive tape to get right down to the surface. After having removed as much as I could this way I painted the whole thing with Lock-tite Rust Remedy, a phosphoric acid rust neutraliser., scrubbing it in with wire wool. Left it to work it's magic for 48 hours then went over the whole thing with 120 grade abrasive and finally gave it two coats of the green outdoor paint that you get from Aldi. This paint has a rust preventative in it and seems to work very well. Also it is tough. With the bigger items I will use my power tools to de rust. One thing I will mention. When I did the propeller shaft I discovered that someone had lathered it with wax oil at some time in the distant past. They had done a pretty hit or miss job of this and the result was that where the wax oil had been applied, the paint underneath was in almost new condition. The rest was lightly corroded. But removing the dried out wax oil was a real pain. It just kept coming back. I finished up scraping it all away. Then used panel wipe to remove the remaining coating. And it still kept re appearing. It took ages to get it all away. In future I think I will burn it off with a blow lamp. Oh what fun we have. Dave. |

I'm using power tools on even the small stuff.... but then, I am notoriously lazy... Got one of these the other day (different brand, but very similar): It doesn't half make short work of rusty bits... Combined with the sand blaster, plasma cutter, angle grinder, air chisel and solvent gun (to soften & remove underseal), it was relatively easy to clean up part of the underside ready for new metal... |

I might buy one of those. Been away on holiday for the last week, so not much done. However, the first thing I did on returning was to take the rear suspension cross member down to the local powder coating place to have it shot blasted. I had cleaned away all the scale. and didn't want it painting. But is is still going to cost me £45 just for the blasting. Hell, that's steep. I doubt it will take fifteen minutes. The only reason I took it in is because of the awkward access to some parts of the thing. You can buy a lot of elbow grease for £45. Dave. :( |
