I have. Performance is about the same but RainX last longer....much longer...

Not sure why. But I also got something like that with any kind of glass protection on, RainX, Rain Act, Rain *whatever*, Aquapel, Rainaway, etc. Not haze...but something like morning dew kinda thing. Normal? Don't know la....

that sounds serious.

you used rain x before right? did that happen to rain x? if no, you know your answer already.

eh what does PRU has anything to do with mood 

no idea bro, i am using meguair's wax 

i thought kura kura is mainstream as hell lol

Giants ada Sonax.

sonax is a very established brand from Germany. dont think you can go wrong with it

check out http://www.sonax.my/ for more info.

You'd be fine with any 'liquid wax' from those well established brand:
Meguiars, Mothers, DuraGloss, Optimum, 3M, Sonax, Autoglym, etc.

As for those Jap/Asian brands like Soft99, TurtleWax, PG, etc....can't really say. I've tried a *very* few with mixed results (or maybe I'm just too easily influenced to the hypes from the 'mat sallehs' brands....).

Paste wax will have better results. In terms of durability and appearance.

But with the weather that we are having now, I don't think you can see the difference.

Freaking hot then suddenly the sky "pee" for a short while, enough to cause more dust flying everywhere. 

Technically...if it's the same made, for example Megs NXT liquid wax and Megs NXT paste wax, there shouldn't be any much of a difference other than application methods and techniques. For example, the liquid waxes are more friendlier when applying it with a machine whereas the paste waxes are normally targeted for hand application.

Other than that, I haven't really ventured into looking for the differences in 'results'. Of all the liquid sealants and paste waxes that I've tried, 'results' are mixed and I haven't observed any one is better than the other except for the above. Unless you're talking about 'better look' (but a little lacking on the durability side), than I would say that paste waxes (in general) could give a better look as some of those that are advertised to have high natural (carnauba) content are mostly paste waxes.

Oh....many people would put on a liquid sealant then top it up with a paste wax to get (so claimed) the best of both worlds (durability + looks).

Just my 2 sen.

LOL...there's really no such thing as 'stupid' questions. And yes, for some reasons, local Megs' prices are really cut-throat.

I think, for a start, it would be better if you think of it another way. Instead of liquid waxes or paste waxes, think of them as sealants/waxes in LIQUID FORM and PASTE FORM. If there are any differences, it would mainly be due to the chemical contents devised to give them their FORM.

And for 'older' cars, may I suggest you find something that can also 'clean' the paintwork - 'clean' as in able to remove embedded/stubborn dirt and stain so that your car would 'shine' better. The cleaner the paintwork or the lesser the defects (swirls, scratches, marring, etc.) in the paintwork, the better the shine. We normally termed these kind of 'waxes' as an All In One (AIO). They would *very* lightly polish, clean and protect the paintwork. Examples would be something like Duragloss #501...and....errr....I can't think of anything else better or more economical....hehehe...

I think same stuff la...just different manufacture use different term. Maybe one contain systhetic polymer (sealant) and the other contain more natural wax.
