What is the consensus on dry ice cleaning and the removal of old Cosmoline?
I am considering getting mine done prior to putting it on the market

You can always get the cosmoline reapplied after finishing the dryicing.

Will it increase value more than the cost itself? If selling, I wouldn't do it, unless ROI makes complete sense.

I think mileage, history and condition, along with options drive the value. Rare models are a different situation. Dry ice blasting makes the underside shiny and perhaps some will see that as a value increment.

Can't believe you're selling. I wouldn't do it.

I personally like a clean underside and would pay more vs one that's filthy assuming all else is equal.

Ice blasting removes and hides leaks and indicators of how the car may have been cared for, where it lived, inside or out, all of which a prospective buyer should want to know. Cosmoline is not an evil substance- to the contrary. It may not be "pretty", but it does its job well.

Saw the process done…..it will make things look new. It can be costly, ie 8 hours times shop rate or about $1500-$2000. May bring extra value when selling but depends on car model.

I didn't think that Cosmoline was still available?

Honestly, I'd rather buy a car with cosmoline still on it. To the previous posters point, I'd like to see any leaks and their likely origin to determine amount of work needed to repair.

Not sure when it comes to selling if result is worth the cost.

I wholly agree! After all, who really knows whether such would affect the sale price?! Answer: it's all speculation! And I, personally, like the protective quality as that was the original intent.

Were I the seller, I would err on the side of "original" (for general valuation consideration) so as to demonstrate the car's excellent care and condition. Whether that next owner will be bowled over or suspicious is all guesswork. I'd say leave it alone if considering a sale.

I just bought some Cosmoline - comes brush on and spray.

Dogs new car is a Subaru Outback - dealer tried to sell undercoating BS, told us the car needed it. Plus the product they used is oil based and sprayed all over - not a good product for rubber items such as bushings and hoses.

Got it home - factory under coating was robust and nicely done except in a few spots. I removed the under panels and brushed Cosmoline on all exposed areas and bolts that could rust.Since I didn't finance or buy any of their extra add-ons, they weren't in a good mood.

I removed it in the 993 because it is not used in the winter and I like a clean car.

Hi Todd,
The factory sprayed Cosmoline on the engine case as a corrosion inhibitor. I would leave it alone.
It in combination with minor oil weeping serves to protect things from corrosion.
The desire to be fastidious, in this case, may not be the way to go.

If the vehicle is never going to be driven in foul weather, especially over salted roads or on the coast, then I'd say removing the cosmoline won't be a factor. But, OTOH, you have no control over what the new owner will do so I'd say leave it alone, then let them make the decision and incur the cost if they choose to do the dry ice thing.

Dont do it, keep it original, doubt you’d recoup the cost and you may actully drive away some buyers. Most buyers searching for a 993 would likely prefer originality.
