Not sure if u guys have done comparison, but clay bar is generally more effective in removing above surface contaminants than clay cloth from my experience. Clay cloth is easier to work with but if your car's contaminants is very severe, then u will be doubling your time and effort to remove the contaminants.

The cons of using clay bar is it can be sensitive to what lubricant u use, some soaps can destroy your clay bar very quickly, and clay bar if drop on dirty surface (like floor or road) and it picks up stuff from there, then its as good as throw away dy.

U can test your claying results by wearing a thin plastic bag on your hand then rub the clayed surface vs the non-clayed surface to notice the difference. The best clayed surfaces will have no bumps feel whatsoever.

This is a useful info. Thanks for the sharing!

Yea I do agree on the point that clay is sensitive to certain lubricant. For instance, I had a 3M claybar + Osren Bubble Wash & Wax as lubricant. It slowly disintegrate the claybar materials. That surprised me.

That's one of the reasons I was sharing info also. Previously I tested Meguiars professional claybar against soap water, and it changes the quality of the claybar over time.

More recently I tested Meguiars consumer claybar with Cartec All-Purpose Cleaner by Rupes Malaysia distributor (thats what they recommend for claying) and it started disintegrating very quickly with just claying 1 section 2ft x 2ft.

Claybars can be expensive, and slower to use due to constant re-folding and flattening after every section, but can clay your entire car many times and achieves a cleaner surface.

What's the symptoms of claybar is disintergrating?

Im not sure if u guys can notice this but the watermark on the windscreen is pretty bad. After wipe, still noticeable.

How to clean the windscreen? Glaco is good?

You may use this to remove watermarks on windscreen/side glasses (http://osren.com/product/coatz/all/04a-glass-polish-abrasive-cream)
Or search for antirain watermark remover from Facebook.

Glaco is water-repellent product. You can apply it on the windscreen to cover up the watermarks (watermarks is still beneath the water repellent layer), but it's not recommended as it might affect the durability or performance of Glaco.

Hmm IMO, I think all-purpose cleaner is considered as strong cleaner (than car shampoo) and not suitable to use as claybar lube.
Probably you can try claybar with meguiars gold class shampoo? I remember it was a good combination for me and claybar was still fine.

My recent combination is soft99 claybar + fireballkorea 1:600 diluted active snow foam as clay lube. So far no sign of deterioration for claybar. Need more test on this.

UPDATE: Found this http://www.chemicalguys.com/Poly_Clay_Bar_...y_202_180gr.htm
" Using low quality clay lubes or cheep detail sprays will deteriorate your bar and lead to poor clay bar performance. Also beware of soapy water as a clay lube, detergent or surfactant based soaps will cause the clay to deteriorate"
Probably the surfactant in the car soap caused the claybar to deteriorate faster?
Ermm it's like when you try to fold the claybar, the claybar will break apart. And some of the claybar pieces will drop off as well, kinda like "disintegrate" from the complete piece. That's what I experienced.

Actually, I find that clay cloth is easier, i reckon that both materials are different too, imo.

I agree that some lubricants used may disintegrate clay bars quickly,
orsen bubble wax + perma glass clay bar = hancur.
Clay bar + meguiars gold class shampoo = OK
Clay bar + turtle ice wash = ok
Clay bar + mothers carnauba wash & wax = ok

But with clay cloth + any shampoo = ok

Difference between clay cloth and clay bars, on neglected cars, both does remove stubborn dirts effectively. Neither one works better than the other, that's my opinion. But i still keep clay bars around for nooks and cervices.
I noticed that clay cloth doesn't hold/stick dirts, unlike clay bars, dirts are trapped in the clay itself. Using clay cloth + shampoo as lubricant, i find that the shampoo would become gritty. and all i have to do is spray the clay cloth once it is used on all sides to work on fresh panels.

both clays feel different too. clay cloth is more tacky, bar is more "plasticine", in a way, a more natural feel of clay.
end results are the same, surface is silky smooth.

can i find this osren product in ACE hardware?

Agreed. APC is generally quite strong. However, that was what was recommended by the local Rupes distributor, I tried it once on my Meguiars claybar and it started to disintegrate, so immediately stopped using. I prefer to use Quik Detailer or Last Touch depending on what I have available at the time.
No worries, I was just sharing experience based on my car detailing shop days. We used both claybars and clay cloths on the same car panels before, and found often the claybars cleans above surface contaminants faster with less effort than clay cloth, but clay cloth advantage is also it can cover greater surface areas before requiring to go for a quick rinse before continue using whereas claybar normally should turn over new surface after every section.

I spoke to my detailing suppliers recently about getting clay cloths, but some of them also not taking new  stock on clay cloths because it is less effective than clay bars (feedback from their other detailer clients).

Quik Detailer is great! It's so smooth when use as the lube!

can try http://meguiarsdirect.com.my/. very helpful, honest, efficient seller

I done mine(M4 package) since august till now. Actually I went back twice to ask them settle some issue for me and they are willing to help without charges. I am not sure the partial recoating free service. For RV, they do apply back the coating for the area for free if polish work is required. at least I went through this twice. Can say most of the time they are willing to help.
And they have a activcare session(cost around RM500) for the outside and interior maintenance which include remove the swirl marks, light scratches and reapply the coating again if not mistaken. I think you will only need to do this if you have serious swirl or scratches issue on your car after apply the coating. RV is using GYEON(korean) product, can online do some research on the products.
My friend has done coating for few cars by RV and the result are quite good. I can see one of his car still looks shinny after 3 years.

However, this is just my experience with RV. Ceramic Pro is quite famous also and can see a lot peoples are using them. Maybe you can get some feedback from any of them first.

Btw, what car you are planning to coat?

Can you share contact/website of this RV and roughly how much it cost to coat a medium size car?
Thanks.
