Rescuing oxidised guards red. Yes I've done it - two weeks ago. Early reds oxidise, we all know that. Cellulose paint, is quite thick but look terrible when white with pink blotches! After several years of trying tcut, machine mop and red wax polish, which lasted 2-3 months I had given up and resigned myself to a re-spray.. My oxidation was very severe not superficial, roof, bonnet rear quarters and bumpers. (Not the front wings as they had been replaced and resprayed before I bought the 944). I'd looked on websites (a lot) but found nothing convincing or a definitive treatment. G3 is used a lot but I was not convinced it was going to fix my problem of frequent reoccurrence. So before a respray I was going to try something more aggressive. Initially I tried 1500 wet and dry followed by 2000 then 2500 on the front trim panel. Not good. 1500 is too aggressive and leaves scratches that are a lot of work to polish out even with a machine. After a 2nd test on a rear wing , I finally found success with the following recipe; 1 Wash all over with clean water to remove any grit. 2 Wipe with white spirit to remove old wax if possible 3 Use wet and dry, rub down panel by panel with wet, 2000 grade, uniformly in long lines not swirls ( this is hard work but essential, red has to be coming off onto the wet and dry and it needs frequent washing down. You get a feel when you are really cutting into the surface) I used my hands not a block. 4 wash down the panel and let it dry. If you still see oxidation whiteness or spots missed then repeat step 3 again until you have a uniform red. You can see areas of white showing gaps between fingers pressing on the wet and dry as it was slid along, clear signs that you were not doing enough. The oxidation does not wet like a proper paint surface so gives itself away. All oxidation has to go without exception! 5 When dry, wipe over with a cloth, all residues have to go. 6 Use G3 . I used Upol 33 paste which was good , but then switched to Farecla G3 liquid as it was more suited to my electric polisher. Don't be afraid to add a lttle water, its not wax. Hand apply. Use the polisher until the panel is a uniform colour and even all over. The polisher is the only way to get evenness over large areas ( you can't do this by hand for large areas unless you are an expert) 5 wipe it down, remove residues, dry. 6 Wax. I used resin wax as that’s what I had and always have used on my other cars, but other polish should be ok, apply by hand, polish with orbital polisher 7 do all the other panels The G3 is superb its nothing like TCUT which is a joke in comparison The important step is ensuring all the oxidation is removed by step 3. If you are a perfectionist there is 2500 wet and dry as well, but I was happy with the results here. Corners and edges can be a problem, professionals mask edges to stop the paint being thinned locally. I had areas on my roof that were down to bare alloy ( on the edge trim) which the previous owner had done, theses areas best done by hand or with care. I tried some photos but its difficult to catch the oxide ugliness in a picture so I gave up but my 944 was 75% pink and now is showroom ( ish) glossy. Of course the nice thing to do would be to lacquer it now but….. So for me the choice of a respray (1k-2k+) at a paint shop or a DIY respray ( buy a compressor then £100+ on paint and learning how to spray then doing it again!) has been avoided by a £10 G3 liquid and £10 of 2000 wet and dry paper. Plus a fiver on a polish waffle pad - not really necessary!.
