Please see here for the initial post.
The below picture shows what were applied.
|Sealants||Water Beading||Water Sheeting|
|Autoglym Extra Gloss Protection||1||1|
|Finish Kare Hi-Temp Paste Wax||1||1|
|Fusso 12 Months Wax||2||2|
|Meguiar's Ultimate Paste Wax||1||1|
It seems that the effects of most of the sealants are starting to diminish. However Fusso seems to be still working but I am not impressed.
True to most of our understanding and suspicion, there are "severe" water marks on the Fusso section.
"The general idea of a hydrophobic surface is that dirty liquid will not "wet" and smear all over the surface. But if those water droplets are left to stay till dry (hard water and/or with some dirt encapsulated in them), there could potentially be water mark".
My wife drives to work every weekday and the car is park under the sky at her workplace. If it rains, the rain water plus surface dirt will bead up on the Fusso section. When the rain stops with the sun coming out, the water bead will dry up and whatever that is inside the droplet would be etched onto the car surface.
So far, I did not see any water mark on other sections. That is why I used the word "severe" earlier. As such, I do not intend to continue this evaluation. As mentioned in the initial post, to have a fair evaluation I skipped using spray wax on this particular test surface. Being a spray wax lover, I believe using spray wax would have minimized the water marks.
As a general conclusion (based on my personal observations and opinion), most sealants tends to last about 3 months in our Malaysian climate. Fusso might seem to be the strongest contender but the high water beading is also its biggest downfall. It does give the "wow" effect but in terms of protection, other sealants might be doing a better job. I think it is quite conclusive that high water beading might not be a quality one should look for in terms of protection in a tropical climate.
I strongly believe that using spray wax after every wash would not only prolong the longevity of the sealants but add to another layer of slickness and protection. So get yourself a spray wax and start spraying! Read about spray waxes here.
That's it for this comparison.
I would like to thank those who followed this comparison and provided constructive comments.
