used PIAA silicone wiper for 6 years on my previous ride and never apply rain-x

never bother to lift up the wiper blade when park under hot sun

after so many years still no issue wiper noise and wiping capability, only normal car wash for the windscreen, occasion wax the windscreen as well with car wax and the wiper still no problem wiping

the only thing i did to prolong the wiper durability is to not turn on the wiper too early as the windscreen is not wet enough, since wiper can get damaged from the dust on windscreen
