always want to replace wipers? Is there a really good profit margin,
or do wipers truly need frequent replacement?
Throughout my driving history going back to 1963, auto techs have
recommended replacement frequently.
In this case, the dealer's mechanic recommends replacement even though
the vehicle has been driven a total of only 7,000 miles in four years
and spends most of its life in a shaded carport. Maybe the rubber
gets dry rot???

I've seen ones on old vehicles that have stood for years where the rubber
has gone dry and crumbly (same with things like door and window seals).
It actually seems to get things left in the shade more than the sun, so
maybe it's made worse by cold / moisture.
I've heard that a soak in castor oil's good for reviving it, but I don't
know if that's a genuine fix or just a temporary one.

Definitely, if the part exists. For a lot of old vehicles (I'm talking
vintage stuff when I say "old cars", not e.g. 1980's clunkers) that isn't
always the case - but although I've had a few vintage cars pass through
my hands, I've always been able to source spares or had good donor parts
handy, so it's not something I've ever needed to try.
I don't know if the rubber goes bad because it just dries - or if there's
a deteriation due to chemical reaction at work, so the oil just gives the
appearance of a fix.
I don't know if it affects *modern* parts, either - or if the problem's
irrelevant these days, but garages still use it as a way of boosting
Caster oil is what you use when your casters are seized and you want to
move a vehicle with shot tires ;-)

Yeah, to be honest I suspect you're right for wipers. In fact, I think I
did that for one vintage vehicle I had (or rather spare blades were just
sold as rubber strips and the rigid parts were retained each time - but
perhaps the profile's different for different cars, so they're not 100%
I have investigated this for my old Studebaker which uses 12" Trico
blades (shared with pre-63 Corvette) and the only thing that I've
found that will work are the expen$ive repro blades sold for Corvette
enthusiasts. I would really like to use silicone inserts but the
profile of the "claws" of the blade is different, and attempting to
trim to fit with a razor blade did not work. Now maybe if I had a jig
to trim them things would be different.
re: "Now maybe if I had a jig to trim them things would be different.
When I think of a jig I think of all the one's I've made for various
woodworking and/or metal work projects. The few hours I spend making a
jig saves me countless hours of layout and measuring when performing
the same task over and over again.
I don't know exactly what type of "timming" you have to do, but
couldn't you spend a few hours making a jig that you could then use
possibly. the problem is that a) I haven't a clue how to make a jig
to do what I need it to do and b) $20 every couple of years for some
overpriced but "show correct" wiper inserts really aren't the end of
I *could* just replace the blades with new aftermarket ones and
sidestep the problem, but I like the look of the old, low-profile
polished stainless blades.
I don't have a good profile pic of old and new refills handy, but
they're significantly different, with the new style being much
larger. If you go to Corvette Central and search for a '62 wiper
blade that's exactly what I'm using on my '55 Studebaker. (it was
actually used 56-64, but refills are available for those, and they're
also 12" long unlike the original '55 blades which were 11" and are
stashed away for safe keeping if I ever decide to restore the car to
show correctness, which will likely never happen.)
re: "and are stashed away for safe keeping"
I assume they're hermetically sealed in a mayonnaise jar under Funk &
Wagnalls' porch, right?
We wouldn't want them to be all dry rotted when you pull them out...
Must be something about your locale. I've lived in 7 states in the
northeast and southwest and never had a mechanic offer to work on
anything but his main task and perhaps engine components like
fanbelts, hoses, etc.
Oil change shops are the worst: they want to pad the bill with
anything they can find that they are competant to fix, yet I've never
had one offer to replace wipers.
Had my car in a tire shop and they pointed out a striped lug stud.
Said they had are relationship with a midas brake shop and they'd
replace it free. Took the car there (mistake!) and they chewed the end
off my axle. It has a one time crimped nut, it has a part on the nut
that is hit with a hammer to crimp it. It is a one time part. Midas
tried to reuse it and chewed the end off the axle trying. Then they
tried to say "it was like that when we started". Had to take them to
small claims court. It was weird calling road side emergency service
to have the car towed *away* from a repair shop.
Oh man can I relate to that!... I go for an oil change at the dealership
and they ask what the mileage is...I give it to them and they say "your
truck needs this, this, this and this" ...I say to the kid behind the
computer "My truck is sitting outside and your telling me what I need and
you haven't even looked at it" (he's going by the odometer reading of
vehicle and according to the computer all these very important issues need
to be done which I think a lot of it is a money grab) soooooooo after
SEVERAL twelve hundred dollar oil changes from that place I started going to
a 'jobber" place and get it done there.
