The dumbest question ever asked

That is not dumb.

If you think this is the dumbest question, I suppose that you don't read this group that often?

I think they make leather treatments with sunblock, perhaps one of those would be good... Although vinyl probably won't soak too much up, so use it sparingly.

Armour-All. Been around for years.

I strongly recommend NOT using Armor-All. Yes, it's been around many years and there are numerous reports of it actually ACCELERATING the cracking of vinyl dash boards.

I suggest finding "Aerospace Protectant" by 303 Products. It was specifically developed for the aerospace industry as a sunscreen for products subject to high UV intensity such as those found on aircraft. It can be mail-ordered over the Internet and some Ace Hardware stores carry it. On the bottle label they call it "SPF 40 Sunscreen for your Stuff". It also works well on the sidewall of tires. It protects the rubber and doesn't leave that slick, greasy look and won't discolor the rubber like some of the tire treatments you buy in the chain stores.

Is there a reason not to use plain old SPF 40?

The substances in many of these products are not extensively tested for their effects upon health. I would rather have a cracked dash than cracked DNA.

Cancer rates are rising.

I am sure it will help prevent skin cancer on your dash.

To elaborate, even the stuff in your SHAMPOO hasn't been tested well.

Well tha gud ole boyz in tha bak seat says they aint neva gonna rub nona thet there stuff on em ta prevent sun burn! An if ya dont go around nekid wif out no shirts, all ya need ta do iz wear a cap ta keep your forhaid naice an sun free an your kneck turns raight dark laik it otta. An them sure did say they aint gonna shampoo tha dash wif nothin but maybe wipin off sum beer whut haz gotten akcidently spilled on it.

NEVER, NEVER use Armour-all on vinyl. That is the surest way to create cracking, especially on dashes. Armour-all is a petroleum product that virtually sucks the polymers out of the vinyl creating early cracking. There are better products on the market but make certain you get one that does not have any alcohol or petro products. I know a guy who "saved" a dash by simply wiping lanolin hand creme all over it several times. I'm almost positive Armour-all was developed by someone selling aftermarket replacement dashes. BTW a good dash cover also works wonders to "get rid" of cracks.

I have a 79 204d, w 3 cracks in dash. I bought a dash cover from Dashmat. Easy solution, works well

No it's not, it's emulsified silcone oil. If it was petrolium based it would say so on the label (by law) and it would burn. Try to light it.

Suntan lotion works too. All these things so is provide a chemical barrier that keeps UV out. In a Canadian winter this couild last weeks. In texas in semmer it might last a day.

I once met an organic chemist whotook two hours to explain all this to me. His recommendation? "I use whateevr is on sale. They all do the same thing".

One exception is "303" which is a water based product and is in effect a sacrificial polymer and acts like a sun block. Developed for the aircraft industry to protect exterior plastic components. "Life's journey is not to arrive at the grave safely in a well-preserved body, but rather to skid in sideways, drink in one hand, totally worn out, shouting "...holy s*it...what a ride!"
