OK, so I picked up a 'Stang as a project car and it will be painted. I've had a few people tell me I should have the car undercoated to protect from rust. The bodyshop guy indicated he doesn't do undercoating, it only locks in moisture. Anyone have any knowledge on this? Also, the car won't be seeing snow, and will avoid rain as much as possible since it's going to be the weekend car, so undercoating may not be necessary anyway. SOrta tech, gray area. Thanks.

I got a 93 coupe out of New Jersey this spring and it has a lot of surface rust under the car which looks like it is from heavy salt use. We don't get heavy rust down here because we don't salt the roads as heavy as you do up there. I did not think the newer cars still rusted like that but I guess they still do but not as bad as the 70's cars did. If you are not going the take it out in bad weather I would not get it coated. If you add coating you will need to remove it in spots if you add anything like subframe connectors.

Subframes are definitely going in.

It's just a pain sometimes to remove and starts small fires when you weld close to it plus could contaminate the weld if not properly removed. Just some things to consider....plus I don't believe Ford or their dealers offer undercoating as an option anymore so they must think it is not needed because they already have enough corrosion protection from the factory.

if the rust has already started it is not going to do you any good to have it undercoated.
If you dont plan on driving it in bad weather you would be better off to just leave it

The car looked pretty clean. The only rust I think I saw was some surface rust on the shocks and exhaust. Yes, the car will only be driven in good weather.

If there is no rusting - and this won't be a DD (as you indicate) you do not need any type of undercoating.

Maybe a fresh spray can of chassis black on some of the leading edges around the floor pan, muffler pocket, etc to keep stone chips from exposing bare metal. In your case, I agree with everyone else, there isn't a need for undercoating your car.

Undercoating, like anyother kind of spray on protection, required proper prep. If the prep is crappy then the undercoating will you no good.

The yahoo that said undercoating only traps in moisture has obviosly never correctly done an undercoating. His logic could also be applied to paint, for that matter.

It sounds like I should be more concerned with dry locking my garage floor than the car's undercarriage.
