10th May 2018: Wings
After a chilly start to spring, the AC emerged into daylight in mid April. Having temporarily reassembled the body last autumn, I decided to tackle the wings first. Stripping paint, making minor repairs and painting the underside. Next, I'll be completing the repaint of the front inner panels and chassis. I plan to try out coach-paint from Paragon Paints, both black and body colour. For the original paint scheme, AC used the body colour paint on the visible parts of the chassis around the jacking-points, the ledges that the bonnet rests upon, and the bumper irons and associated bolts. Paragon paint looks as though it will work for those steel components, including wheels. When the time comes, I hope to use Tekaloid coach-paint for the body panels. I'll update the restoration section in due course and let you know how I get on.
10th August 2018: Coach-painting
Blessed with fine sunny weather for many weeks, I've been busy painting inner panels, brackets and numerous fittings. As mentioned above, I tried out Paragon Paints so-called coach-paint, where I need a nice finish on steel parts. That was a disaster! It might protect against heat, acids, etc., but the brush-marks are very bad indeed. At least it's handy on small steel parts, since it does not need primer.
So I hastily purchased some Tekaloid coach-paint which fully lived up to its reputation, as brush-marks disappeared within the first few minutes after applying. There have been no shortage of niggling little problems when trying to paint both sides of brackets, as the paint (especially the clear coat) remains very delicate for some days and is easy to spoil. I will write it up in detail at some future date, but for now a few points about colour matching might be of interest.
When trying to establish the correct body paint colour, from the faded original paintwork, there are a few points to consider:
1 - When the surface of the original cellulose paint oxidises, it turns brown. In the case of my light green AC, it changes to a khaki colour.
2 - Certain colours are unstable, including the shade of dark blue used on many ACs, creating a wishy-washy mix of shades.
3 - As any artist knows, colours look more pale, and weak, the greater the distance it is viewed from, due to moisture and dust in the atmosphere. This effect is greater than you might expect even from a short distance. If you take a small panel indoors, examine it closely, take photos at close quarters, it is surprising how dark it looks - especially for lighter colours. It is also important that it is not reflecting any strong surrounding colours, such as blue sky or artificial light.
With the above in mind, I used paint from inside my door openings, as a reference, since this was only partially faded. I identified it as colour number 278, from the BS 381C range, known as "Light Olive Green". AC called it "National Grey"! I took the risk of using my close-up photo of semi-faded original paint, to compare with online colour charts. On-screen and photo colour matching is not as inaccurate as it used to be. I did buy two BS colour charts previously, only to find that light olive green was omitted! Thankfully, the colour is an excellent match, with a much more vibrant look than the faded version, but pretty close to the less faded areas of the old paint.
Here is a bumper selection of photos of new, shiny paint - all brushed, not sprayed!
