Bloody hell, that's an amazing detailing job!
However, I am wary about this entire "wet/dry sanding" thing... will it/ won't it strip the top coats of your paint?
Does it also mean that you have to constantly wax it, after sanding, to keep it from corroding?
Hi The Necessary,
I'll just chime in a bit about wet/dry sanding. It's actually a common process used even at the paintshop level to correct certain paintwork defects. FYI, it would probably have been used on your car from primer, basecoat and/or all the way to the clear coat level (which is what your paintwork would consist primarily of). Over at AutoDetailer, we specialize in this particular detailing subset to create sharper image reflection which is termed as DOI or Distinction of Image. Take a look at your OEM/refinished paintwork and you'll be able to immediately spot what we call "orange peel"effect which comes as a standard feature!
Essentially, wet/dry sanding eliminates the high points of the clear coat knocking off "peel" effects on the clear coat itself. This is done using specialized tools and specific resin-bonded sandpaper that runs between 1,000 grit all the way to 4,000 grit. At 1,000 grit the sandpaper feels a bit like your average A4 sheet. Extremely fine. Using a random orbital that "orbits" and "skips" instead of consistently going around in a rotary-like manner allows the surface to be skimmed.
Next comes the buffing process which is extremely time-consuming. Quite a fair bit of showcars/display cars in exhibitions, photoshoots and private garages are done at our detailing center and requires typically 1-3 weeks to complete. An indicative cost for a proper wet/dry sanding finish of this calibre would cost between RM 2,000 to RM 3,000. Not cheap but extremely spectacular for a finish!
I do have to emphasize that this is a very skill-specific and specialized area. I've seen a fair share of cars sent to us for corrective work and/or ultimately repainting because the owner's placed it in the wrong hands.
N.B. Maintenance for a wet/dry sanded car is just like any other paintwork. Regular good-old washing and waxing helps to preserve the finish JUST like any other detailed car. Remember though, proper wet/dry sanding detailing is done at the clear coat level for an OEM or refinished car without harming the basecoat. It will not induce corrosion in itself.
HTH!
Cheers!
