Undercoating - Inner Fenders

[Shakey]

I am preparing to spray some undercoating in the next few weeks under the fenders and along the inner fenders of my '69 Charger.

My question to you folks:

What is the proper area that is to be sprayed?

Attached are a few photos of what some others have done (you may recognize these two cars), neither one the exact same.

What have you done on your car?

I have already chosen the product, the only question is what areas should be covered and what areas should be left alone.

Thanks in advance.

And here are some photos of another car for comparrison.

Hello again Shakey,also like the rest of my car ,still has all of its original sheetmetal including inner front fenders,fenders,trunk floor,floors,valance,valance corners,etc.,and all the undercoating was mint and not falling off so I chose to leave it all as it does not get any more original than that.So here are some pics of the outside of the inner front fender aprons as the factory undercoat remains.What i did was clean and prep the painted areas,epoxy primed everything,including the undercoat,basecoated onto the undercoat a little bit,and then cleared.Now i will go back with black epoxy with a small touch up gun and repaint the undercoat,using epoxy as not to make the undercoat look thicker or heavier than its supposed to be.As you can see in the pic,the factory did not spray the undercoating right up to the upper control arm tray or onto the frame rails,just a note.

Awesome stuff!  Thanks.

I don't want to go overboard with this undercoating but I would like the car to be well protected.

Great photos and a swell job on preserving that finish underneath.

Thanks again.

How about your inside of the front fenders?Do you need pics of that?

My 68 was undercoated alot heavier than that.  It went down onto the frame rail, and was right up to the shock tower, more like the green car.  My front end inspection covers were also undercoated.

Here is my '68.  Kinda sparse on this area, but heavier on the fenders, and more complete coverage, like Too Quick mentioned.

Different body style, but the principal is the same. Aim in the general area you want coated and close your eyes, then pull the trigger on the schultz gun.

Thanks again for all the feedback folks.  From what I have seen, it seems that some cars had more coverage than others so in the end, I chose to do what I felt would look best.

I used Eastwood's Rubberized Undercoating.  We applied a coat on the splash shields a couple of weeks ago to sample it and we were quite pleased with the finish as well as the ability to control the spray.  Costs around $17.00 CDN per can, not much different than the products Car Quest was offering.

Below are some photos of where we applied the undercoating this past weekend.

Just close your eyes and hold the trigger down like they did at the factory.

Seriously though, I don't think it's something that's considered an exact science by any stretch. The guys at the factory were just making a living, not a future classic as far as they were concerned.

I have factory undercoating on mine and some of it has come off. I also have to spray it on some of the spots where metal has been replaced so I'm planning on shooting it all over. The problem is that most of my undercoating is brown (which I assume is dirt) so I'm going to have to find a way to clean it somehow before I spray. How am I going to do that? I don't want it too nice or I'll be scared to drive it.

We didn't want to close our eyes as we were being quite specific as to where we wanted the undercoating.  I realized that the undercoating varied from one car to another so I just chose the areas that I wanted covered.  I don't care about judges!

As far as yours, I would look into a similar undercoating the factory used (the Eastwood's product is a bit thinner) and touch up the areas that need it.  Bill had mentioned a 3M product in the other thread (inner qtrs & wheel wells) that is close to the original.  After filling in the missing areas, maybe a thin coat of the Eastwood's over everything would work.  You still might have to clean a bit of the dirt off but if you're gonna cover it, you won't have to be too detailed.

Boy do I feel stupid!  I always thought that texturizing was something someone did to the car and not stock.  Although, the cars quarters are original and not worked previously, I just assumed this was NOT stock, as it is odd looking.
