To my eyes, the "after" shots show improvement over the before condition of the paint.
I have found via experience that old MG's had horrible factory paint. That is they just never seem to take to polishing like paint on other cars from that era.
I owned a couple of Spitfires from the 1970's and I also don't think the factory paint on these cars was very high quality.
So that could be part of the equation. If they've been repainted then that's another story.
So real quick... the idea behind rubbing out old single stage paint that is important to you, (for some people it's not important), is to push the trade secret oils found in products like #7 and #3 into the paint where they will rejuvenate it. By rejuvenate I mean moisturize it because single stage paints dry out and also reinvigorate the pigments to restore the full richness of color.
It is my opinion that if saving original paint is important to you then you are better off to do this heavy saturation rub-down of the paint with the #7 BEFORE you do any compounding or polishing to make the paint safer to work on.
So AFTER rubbing and saturating the paint with the #7 THEN proceed to do some compounding or polishing to both remove dead paint and in the process also remove swirls and scratches, (below surface defects), and THEN hit it again with the #7.
The reason for the second application of the #7 if you compound and/or polish the paint is because you will have abraded the #7 treated paint off the car.
No you want to re-apply to again, moisturize and reinvigorate the pigments to again, bring out the full richness of color.
Then seal with a wax.
Ive done the above so many times in my life I cannot count nor remember all the cars I've performed this process to but a lot.
SOMETIMES it doesn't work. When it doesn't work it's not because you're not doing something right or the products don't work it's because the pigments have become
unstable or the paint as a whole has is
past the point of no return.
If you own a copy of my first or second edition of my how-to book there's a section called,
Paint Condition Categories
In this section I clearly define category
#9 Unstable and
#12 Past the Point of No Return.
If anyone reading this into the future doesn't have a copy of my book I can tell you first-hand its jamb-packed with tons of information like this. But I digress...
So after you have done the saturation step, try doing some machine polishing but ONLY use quality compounds and polishes.
I say this all the time on this forum, here goes again... when working on thin, delicate paints, be they single stage or clear coats....
Don't skimp on compounds and polishes.
That means,
Don't skimp on abrasive technology.
Abrasive technology is the most important factor as it related to you success or failure when polishing paint. Some guys say it's technique. I say they're all wrong. Technique is a factor of course but what's more important is the abrasives being pushed over the paint surface.
When it comes to single stage paints, not only is it the abrasive technology it's also the carrying agents for the abrasive technology.
Cheap compounds and polishes use solvents that will leach out the oils in single stage paint which dries them out and accelerate oxidation. It will also leave the paint looking dull.
Questions
So what do you have for compounds and polishes?
What do you have for pads and tools?
