[QUOTE=kevcules;937897]Of course you should undercoat your vehicle, unless your not going to keep it very long.
I undercoat my own vehicles now and lots of people are asking me to do theirs also lately. I guess I'll have to buy some more stuff!
I shake my head when I hear people saying they don't like it when the undercoat creeps and makes dirty spots on their vehicle, mainly under the doors and at the fender joints. That's EXACTLY what you want to happen! The oil creeps into spots you can't see or get at. If you don't like it , clean it off, but rest assured that it will never rust there,especially if you leave it alone till spring!
If I had my car undercoated and a week later , I didn't see any creeping on the outside, I would never go back! I use a dripless oil similar to the green cans of rust check and it creeps real good. Dripless doesn't make as much mess when your aplying it.
Makes me smile when I see the underside of the doors get black!!
I couldn't agree more! My '93 Jeep Cherokee that is still running great was used for winters only but I used Krown for many years. Solid floors, rockers all original. I just applied Krown yesterday on our new RAV4. I don't care what Toyota, GM, Nissan etc say, you have to use a good rust proofing product where high salt is used on the highways and I don't care if it drips all day and night, it is doing it's job. If i was leasing then i wouldn't give a .... but since i am keeping this vehicle for a long time I want to protect it the best that I can. So to answer your question, yes do spray it but use a proper product that is applied to all areas and not just spraying with a can. Your not getting into all of the hidden areas where salt lives.
