Suggestions on how to remove vinyl lettering

I recently bought a nice 20' enclosed trailer. The previous owner was using it for his custom chopper buisiness. There are some very extreme graphics on the trailer that I would like to remove. Flaming skulls and the like.
Is there a product available that makes removal an easy process. Something that I can apply that will not harm the painted finish?

I've used Goo-Gone and Goof-Off (creative names for sure) to remove pin striping and bumper sticker residue. WD-40 might work too. There is something called Vinyl-Off 10-4 too (http://www.storesonline.com/site/651327/product/104-008). Use a hair dryer to soften the vinyl and peal it off first aided by a plastic bondo applying spatula. If its a large area 3M makes an adhesive remover and a "decal eraser" wheel - available from body supply and paint shops. The decal eraser goes on a drill -- its mean to remove decals from metal though (is the trailer siding vinyl plastic or alluminum? - if so I wouldn't use it).

Oops! Just wrote the same stuff as Wolfgang. Good advise there....

WD-40.

mayonnaise is the cheapest and easiest.

and it tastes good too.

Hair dryer on high heat. Don't keep it in one stop to long. Just heat and peel that simple.

If you are removing vinyl graphics from a factory applied paint,
Easy Off Over Cleaner.....I kid you not.
Try it on a non visable area, let it set for 5 minutes or so and watch it lift the vinyl then squeegee it off with a flexible plastic body filler spreader, you'll be amazed. However, you'll have glossy areas of paint showing where the graphics were. ~Alan

3M Adhesive Remover. Available in auto parts stores and some hardware stores.

I have a heat gun that I bought at Sears almost 20 years ago. It gets much hotter than a hair dryer. It blows less volume of air but produces much more heat than a hair dryer. Don't stick around excessively long in one place as it will actually soften paint.

I get a couple inches of a corner hot until the edge starts to lift. Peel it up with my fingernail and stick the now-loose corner onto a popsicle stick. You can use anything you want for this part, but popsicle sticks are something that works well as do tongue depressors etc. Roll the decal onto the stick. The glue will hold it on.

Now you have something to pull gently with as you continue to heat the decal. Need to alternate heating the top and underside of the decal while keeping tension with the stick.

After the decal is removed, let the paint cool completely. COMPLETELY!! Then goof-off or any type of adhesive remover will take off the rest.

On large decals, or decals that have been on for a long time, there will be some paint discoloration. You can polish the panel to blend most of that away. Very old decals will probably always leave a ghost image. Don't buff the paint off, give up if it doesn't polish out pretty quickly.

This works on any decal, but is a system that works VERY well on large decals without damaging the paint.

Oven cleaner on Clear coat NOT ME!! I highly recemend the NAPA Klean EASY its safe for Clearcoats and a fresh coat of wax to minamize ghosting in the finish. sunlight will do the rest.

Easy off will not affect the new poly auto paint finishes. It will destroy enamel paint . We used it to remove the painted enamel lettering from the race cars before vinyl became popular. It is also great to take spray paint off a car that prankster sprayed rustolium paint on. Body shops will charge you a fortune. I have fix that problem for under $5.
