Wiper blades & heat

Is there anything I can do to prolong the life of the blade besides trying to park in the shade?

I don't have allot of shade, it's been over 100 most days, where I live it rains 2-4 days a week in the late afternoon (torrential downpour). I think I might be buying blades once a month. Except for Rockauto, good blades are not cheap.

The folks in New Mexico & Arizona must be familiar with this dilemma.

Oh yea, we are.
I found the RainX brand blades last about three times longer than all the others I tried.
I used to have to replace them every 6 months or so since I have no shade to park in either and the last set of RainX has made it well into their second summer so far and still work great.
And I HATE messed up wiper blades, so :D

Like you said, not cheap but if I'm going to buy something not cheap it's nice that they last 3-4 times longer.

I keep a mental list of the best longest lasting products on the market that I use.
RainX for rain on the windows.
RainX wiper blades.
Dunlop dirt bike tires.
Felpro printOseal gaskets
Permatex sealants
3m adhesives.

Well, you get the idea. :D
