Topper Testing Take Two

Three week final review

It’s been a little over three weeks since I applied the SiO2 toppers. There has been rain, the car was washed once (Reset), and survived Hurricane Matthew. I gave is a wash with McKees N-914 and then sprayed it with distilled water and here are the results...

There is still some beading, but the surface is no longer slick. All four look the same to my eyes. I’ll hold off on further discussion until I finish testing some of the other SiO2 toppers.

RLM, I assume you got a lot of rain from Mathew? If so, that obviously may have been a worst case weather test for these toppers.

Lots of rain and no power for 3 days. I had planned on a two week test, but the hurricane pushed it to 3 weeks. Manufacturers are all over the place with their estimates of durability for these toppers. Some won’t give any timeframe and others say months. There are too many variables to say for certain how long a topper will last especially if it is over a coating. How can you tell if the topper is gone and the coating is providing the beading? This is one of the reasons my tests are on bare paint on a daily driver that sits outside 24/7. I’ve got one more set of toppers to test and then I’m going to put everything together in one post and give my final results and thoughts. It’s been fun so far.
 
Is lightly misting the panel with distilled water really the best way to judge? You always seem to get weird beading even at the beginning. Spray hose water on shower setting straight up in the air to mimic rainfall.
