Painted Pinstripe Removal
 
Hello Folks,

My 2001 Ford F150 Lightning pickup has a painted pinstripe (applied by the previous owner) applied all along the top of the body line. Over the years it has become faded, and in some spots it has completely disappeared.

The original red paint is otherwise in excellent condition.

I would like to remove the remainder of the pinstripe - is this something I could do, perhaps with careful use of polishing/rubbing compound?

Thanks in advance! :thumbup:

Cheers, Ken in SSF

You need to "cut" it off the top of the paint. If you polish it off you will also be polishing the surrounding paint the same amount, correct? That would NOT be good as you would go thru the clear about the same time you go thru the stripe. The stripe may cut faster being it is likely not a 2K cured paint as the clear is, but the clear would most certainly be cut as you are cutting the stripe.

So to remove the stripe your first plan of attack would be simply rubbing it off with a rag with lacquer thinning on it. The stripe is often simply enamel striping paint that will wash off with lacquer thinner. After washing it off you then polish the clear to remove any texture difference or remnants of the stripe.

Another minimally abrasive method may be a clay bar. I have been amazed at what this very interesting tool will remove. You can pick one up at a paint store, Magic clay is a brand name but there are others.

Clay Magic Clay Bar - Blue Fine Grade, CM-2200 - Detailing.com

This clay wipes off anything "stuck" on a smooth surface. I have used it to get direct overspray off a plexi-glass window with no damage what so ever to the window, how about cured urethane primer overspray off a car, again, totally removed it with no damage what so ever. No cutting, no wearing of the clear like polish or compound would do, it really works well and may take it off, I have never tried it with a painted on pin stripe but I wouldn't be surprised if it took it right off.

The next step after those fail would be to sand it off. Using very fine color sanding paper like 1500 with a block, a narrow block and carefully sand only the stripe so the surrounding clear isn't sanded. You can do this with a block because the block is going to hit only what is highest, unlike the polish compound that is cutting everything, that is the difference and a BIG difference. If you are careful you can cut just the stripe off with very little effect to the surrounding area and then polish the clear back to a shine.

Here is the block that I made years ago for such work, I got a regular old 3M block and cut it with a hack saw. This little one inch wide block works great for stuff like that stripe.

Brian, you post excellent advice on that stripe removal. I, as a Ford pickup owner, have to caution the OP that whatever he does, be well aware that the original paint/CC is very thin as I've had to 'attack' the tail gate on mine (probably the same on all late vehicles now days). It almost might be a better choice to either have that stripe repainted (over coated with new) or use tape stripes.

i used to work for a harley dealer we always got trade ins with pinstripes. easy off oven cleaner takes it off does not harm the paint at all

You are right Dave as removing those stripes is a VERY tricky project, even for a pro who has done it a bunch of times, it's the open heart surgery of paint work.

Be carefull with this, easy off will take enamel and lacquer down to bare metal! I just used some to break down 50 years of grease on my 55 Chevys engine compartment. After setting overnight I pressure washed, It did a great job on the grease, so good the frame is now bare metal! Probably the modern paints are more resistant to it.

Thanks Larry, I forgot to respond to that, yes Easy off is for cleaning ovens not for delicately removing pin stripes on your beautiful truck. It may have a place in the garage but this isn't it!:nono:

i once worked for a guy that knew everything.

We aren't talking about knowing everything, we are talking about the odds, we are talking about taking a chance that could get you into real trouble. It may very well work but this isn't the place to suggest it.

But you know what, I am going to do some experiments with it and see. How do you like that?

hey, I thought you discouraged home chemistry? :D

For accurate results you will first need to buy a 2001 Ford F150 lightning pickup with original paint, On second thought I may just need to do some experimenting myself.:)

How true, how true. And are we SURE the OP's truck is original paint?

Yep, picked up a can on the way to work today. I lucked out in that I had the rare painted on stripe on a junk fender to work with. This is an original paint Saab example.

I sprayed it on and let is set a few minutes. I was atonished to see that it did soften the stripe and some of it rubbed of with a little elbow grease.

http://i200.photobucket.com/albums/a...psb5bf4237.jpg

But it had a long way to go. So I sprayed it back onto that spot I wiped off and let it set a while longer, 15 minutes or so.

I wiped it off and I'll be damn a lot more stripe came off! I was pretty surprised at this, could I NOT know everything? Damn, this was shaking me up a bit. I was under the impression that I DID know everything and this was kicking my worlds butt!

As I wiped it off it looked like friggin wax for goodness sakes, it put a SHINE on that paint, it was like it was magic. But I noticed that the rag had a little drag as I went across that area where it had been sprayed with EasyOff and not the surrounding area...hmmmm. Yep, I rubbed my fingernail across it not viciously mind you, just a little rub and sure enough the clear has been softened quite a bit! You can see the dark spot just to the left of where the stripe is almost all gone where I run my nail. It was most certainly softened!

http://i200.photobucket.com/albums/a...ps04885ba4.jpg

My vast knowledge of autobody and paint had been redeamed, I DID know it all! WHOOO HOOOO

I also put it on a headlamp, it softened the clear that is on the light staining it. (Yes the plastic headlamps have a clear on them from the factory). I put it on a black out tape, yep it softened it staining it terribly.

Could it work if you simply had an original equipment Harley gas tank, sure. You have nothing else to get overspray on, the clear may be a little tougher, the stripe may be a little weaker, sure, it could work. No one is saying anyone is "wrong", what we are saying is that it isn't a something to experiment with, which is exactly what we are doing just as I did on this junk Saab fender and the other parts, experimenting.

If it was to be suggested VERY strong warnings need to be given as well so the poor guy who hears "EasyOff oven cleaner will take those stripes off" doesn't go out and spray the stuff on like it's the magic holy grail of stripe removal and he ruins some plastic parts or it attacks the paint because it wasn't original and as tough as the original would have been.

Thank you oldndusty for giving me the chance to try it out, I have heard this over the years and always totally discounted it but I can see where it could work. I asked my co-workers what they thought about it and one of them said he did know of guys using it on bikes to remove not only paint stripes but also anodize off aluminum! So there is a warning for you, don't get it on ANYTHING but the painted surface around the stripe!

Sodium Hydroxide used to be the active ingredient in dip tanks.
It is a common ingredient in oven cleaners.
Also called Caustic Soda.

fyi:

It is a quite dangerous chemical in its pure form, normally stored as a flake.
Interesting fact, as long as your skin is dry the flake can lay on your skin with no ill effects. Don't sweat or the burn will start in a hurry. In pure liquid form it is very dangerous and most industries try and avoid it if possible.
When mixing flakes with water, put the full amount of water in a container, then slowly add the flakes. Never the other way around.

try wetsanding with swome 1500 - 2000 sandpaper... go in circles... use ALOT OF WATER... maybe a sponge to help keep it from being too abrasive.. u can also add some liquid soap to keep it from clogging the sandpaper... every so often dry off what you are wetsanding with a towel or any kind of drying utencil to see how far you've sanded down... painter of 12 years
