In my experience the pads that come with a machine are generally no good. Look at Lake Country CCS foam pads if you want the best, Rupes and Shinemate also make excellent foam pads.
Due to the lack of standardisation across pad mfg’s, every company will follow their own colour coding to grade aggressiveness. The stiffer the foam, the more aggressive the pad. Aggressive pads are paired with heavy cut compounds and soft pads are used with fine cut polishes to refine after the compounding step. There is no hard rule though and you can mix and match to suit the paint type you’re working on.
With LC, the yellow and orange are the heavy cut pads and blue and black are soft finishing pads, with other colours falling in between. With Shinemate, the green is the most aggressive one with red and black being the softest. If you want more info on LC the colour grading system-

Will suggest checking out the Shinemate EP-820 rotary whenever you’re ready to upgrade your machine next, one of the best polishers I’ve used till date, as good as the Rupes LHR-19 and well priced too.

Wavex clay is very aggressive, also tends to break up into little pieces after awhile. It will work but ends up scuffing the paint too much. One lesson I learned long ago was to stay away from cheap clay as it can really scratch paint, or it doesn’t last.
I’ve never tried their clay lube but imagine it will be in line with the quality of the rest of their offerings (read low quality). Just use your favourite car shampoo diluted with filtered water in a spray bottle as clay lube.
Simoniz makes excellent clay as do other high quality brands, Carpro has a decon block as well. Pay attention to the colour, you want blue/gray clay as that’s the fine grade. Stay away from red as that’s very aggressive and will leave deeper scratches in the paint. You still have to polish after any clay though, fine or aggressive.
Note: if your car has any bonded tar/ferrous contamination, remove that with tar and ferrous removers before starting the clay step otherwise you risk deeper scratching.

There are quite a few in Amazon and Flipkart, but not much with reviews on efficiency for this purpose (As they are mostly leaf blowers), and warranty. |
This is the most powerful cordless leaf blower I’ve used, works great for drying cars. If you’re doing more than 1-2 cars then you might need additional batteries.

- If certain parts of a car are mildly abraded due to repeated touch (say near the door sill trims or the door handles), how should that be sanded/buffed/compounded/polished/waxed so it stays for as long as the original paint does? Does it have an effect similar to re-painting?

1) Contactless dusting with a powerful leaf blower is fine, cleaning with just water is also fine provided you don’t touch the paint (use a pressure washer or garden hose).
If you want to do a contact wash, use a good quality foam shampoo in a foam cannon attached or to your pressure washer. If not, use soft water in a bucket and mix shampoo in and wipe the paint with 5-6 wash mitts, using one side per panel and switching to a fresh side every time.
Do not rinse the mitts, use a fresh mitt once both sides are used. This method is called the multi mitt method and is the safest method to wash your car without inflicting swirls. Safer than 2 bucket method and eliminates the need for a second bucket or grit guards.
Note: spend as long as you want thoroughly rinsing the paint with water until you’re sure you’ve removed 90-95% of the contamination, only then proceed to the contact step of washing with shampoo.
Also, if using only water, do not wipe the paint after rinsing as water is not a good lubricant (it’s a solvent).
Use a leaf blower to dry, you will need to wipe the glasses down but the rest of body can be dried using air, if it’s ceramic coated, this takes under 5 mins and is much safer than towel drying. If you must use a towel, only dab on the surface, do not wipe.
(If you’re not doing the shampoo/contact step, you will see a very fine layer of road film still stuck on the paint even after through rinsing with water and drying with the blower, this is normal, do not try to wipe off as you again risk swirling.)
Regular cleaning is healthy for the paint and any paint protection you have applied as contaminants cannot build up on the surface, waxes and sealants (and coatings) will last the longest when washed safely using a gently pH-neutral shampoo and soft water.
Only exception being right after you’ve applied the wax/sealant/coating. With ceramics, do not wash for the next 7 days, with waxes and sealants read the bottle label. If not mentioned, wait 48hrs before exposing to water and you’ll be fine.
2) How to fix:
- Clean area with all purpose cleaner/diluted car shampoo
- Clay area are to be polished
- Use a heavy cut compound like Menzerna 400/3D ACA paired with a heavy cut pad
- Refine with a fine cut polish like Menzerna 3000 paired with a soft cut pad
- 25% IPA wipe polished area
- Apply your wax/sealant
(If door sills have any glue reside, first use a glue remover to clean before doing the clay and other steps.)
Polishing paint to remove defects is not the same as repainting. Here only a small top layer of clearcoat is removed to level off the scratches and restore gloss and clarity to the paint. When we repaint, we’re removing all the layers of the paint right down to the metal and applying fresh primer/base/clearcoat. See graphic below illustrating paint correction via polishing-
