Toyota Undercarriage protection

I recently bought a 19' TRD OR and purchased the factory "undercoating protection" plan. I have not brought it in yet to get the undercoat spray but will in the next week or so. Has anyone had this process done to their truck? I currently live in New Jersey where the salt and brine is prominent in the winter. Does anybody have any advice on this? When I purchased it the material the dealership showed me looked like a rubber based adhesive. Thanks!

 

I’m not exactly sure what you purchased... but DON’T do this..!

That was my concern as well. I paid almost 400 for it, not realizing what it actually entailed. I think you are right, a good rinse and some fluid film should do the trick.

 

Rubberized stuff isn’t that bad. The problem like in the video above is people get it sprayed on a few years after the truck is new. The surface is dirty and may already show signs of rust. You get it sprayed and it starts to crack and peel because of poor adhesion. Then water and salt get behind it and get trapped. Oil based films wash away, and hold dirt. You have to apply atleast once before winter, recommended to do it twice per year. Personally I like the rubberized stuff putting it on when the truck is brand new. It’s a lot easier to work on. You’re not getting the shit all over you. Doesn’t cake dirt like oil and fluid film. I recommend applying every 2-3 years or just touching up spots that need it. This way it’s not super thick and less chance to crack and peel down the road. Nothing is going to completely stop rust. It’s impossible to get either product completely covering the frame and it holding up over time, without putting it on a bare frame. They are just products to buy you more time. If you live in the north, unless you wash your vehicle after every drive in the winter and keep it in a garage, odds are after 10 year or a little longer the frame is gonna start to look like shit regardless. And with how bad these Toyota frames are it’s going to be a crap shoot for the long haul anyway

 

Dealers usually use a solvent based (vs rubberized) undercoat. It stays soft so does not crack and thus trap water.

I spray the frame down with body cavity wax, it does not make the truck stink like a chemical factory and dries enough to not attract alot of dirt.

 

Seeing stuff like this makes me glad I'm in California. Political opinions aside. My jeep was 17 years old when i sold it and didn't have a lick of rust and it was not very well taken care of it. Only corrosion on it was the Aluminum transmission housing and thats because I put one in that came from Massachusetts. The old one looked new once you scrubbed the dirt off.
