The windows and therefore the window rubbers on my 55 F350 are original . What is the best way to keep the rubber pliable and functional and to keep it from cracking?

Is Armour All good or does it have some side effects? Baby oil? Or some other conditioner?

 

I wouldn't use Armor all , I think Vasoline petroleum jelly would be best abe,

 

I have replaced all rubber in my truck 10 years ago, and periodicaly wipe it down with tire "wet look" product.

I think it helps.

Keep it out of the sun

 

This has been recommended many times on other forums:

Ross...I got some samples of this product in a goody bag at a car show but never tried it. The spray looks easier to use than the small bottles that I got. Just ordered a spray bottle to try, thanks for the tip. UV is a killer for sure.

 

I have used this stuff on some older rubber on my slick build works ok on softing up but is not a cure all. I bought some nos rubber shift boot and it failed to prevent cracking so buyer

I don't know if it has silicone in it

 

How true!. I think this truck had been stored in a barn when the farmer wasn't using it. I have one garage and my 54 is in it. I am renting a garage for the 55 for Dec thru March.

Thanks for all the tips... so the general consensus is to not use armour all, right?

 

I don't think anything will "restore" old rubber. Even stuff that's sat on the shelf is likely to have lost some of the polymers that keep it soft and pliable.

PS -- Is this the 303 that should be used: https://www.goldeagle.com/product/30...eal-protectant


I saw some stuff at Walmart once for making windshield wiper blades soft again. Out here we only use them a couple times a year, and they get hard as rock sitting against the hot glass the rest of the year. Anyway, the Active Ingredient in this stuff was ethylene glycol ... antifreeze.

 

Rubber is degraded by heat, ozone, and exposure to sunlight. Armor all makes rubber look pretty and, typically, age quicker.

 

I have had good results with the 303 and not so good with the armor all.

 

Instructions for use recommend application every 3-5 weeks...I am lucky to give it a bath that often!

 

I don't know if it's snake oil or not it seemed to help on hard rubber(thinner)but I don't know how it could penetrat, it looked better

 

Inside a vacuum sealed bag and stored in a cool, dark place. ;-)

 

Hi Coach. Polishing briightwork and working on a few rubber pieces this week. What did you end up using on the window rubbers, and how did it work? Thanks in advance.
