under coat experiences

Gentle men. Been a member for a while. Just creeping around. You guys got me inspired to do some upgrades to my 2003 with 193k miles I made the executive decision to keep her since I have had no issues with her. The frame I addressed first. Toyota sprayed it as part of the recall and it had a good bit of general old surface rust. I decided to get her undercoated by a guy so I could stop any further damage. It looks like a fine job, everything underneath is black..... everything. he descaled all the rust off and uses what looks like tar, i don't think it ever fully hardens. So my question is. has anyone had any experience with getting their trucks undercoated? I have noticed that getting the shit off is a pain in the ass now to work on. I guess its a trade off. I love the truck too much to trade up to a 2nd gen

Do you guys feel this was a good move?

 

You could post some pics if you aren't sure it's 'normal', but if you search you'll find lots of accounts already on TW regarding undercoating.

 

I think its ok, I need new leafs I dont think they are suppose to look like that. Getting at the bolts seems to be a pain in the ass due to the coating. Just wondering if that seemed more the norm with this stuff

 

Do you want the truth about doing this to an old truck ? It's like painting a wooden ladder. It is still going to rust and decay underneath.

 

I agree, however its my favorite wooden ladder. There is not a spot of rust on the body and not a lot on the frame. I want to keep using it for hunting, bad weather traveling, wood hauling etc, not my every day commuter. These trucks just get to damn expensive when you want an new, or something a few years old. Plus I love the small size for all the tram roads and tight off road use that I do. I just hope putting some money in to her gets me 5 more years or more. at this point I think it will be more mechanical issues than body/frame issues. I have seriously put very little money into her except general upkeep. Just wanted your guys thoughts.

 

Start Fluid Filming it. Stuff creeps where paint or surface coatings cannot. As an extra measure put a can or two of Eastwood internal frame coating inside the frame rails. All good stuff.

 

You don't live in a particularly bad area for salt so what ver you did should not be too bad. But, generally speaking avoid tar based products and use oil base that does stay liquid and has to be repeated. Rust starts from the inside out. What you sprayed is only part of the area. I hope they never spray that gook up into the body drain holes .....;-(
If you spray on biodegradable motor oil, it will help keep the areas soft and will definitely flow better into any crevasses that may appear better than anything else. Spray it also up into the drain holes of doors and all body panels from a dedicated garden sprayer. It's cheap and nothing works better.
