i love my gta but i carnt be arsed washing it every week so take it down the hand car wash. the other day i did it myself and gave it a wax. there was a small italian flag under the gta badge which was on when i bought it (about 1inch x 1/3 inch). it had started going funny round the edges i think it was the grit from winter. it was quite loose so i just gently pulled it off. the paint is still fine however there is a brown 5hitty mark in places round the edge i set to it with the sponge and shampoo but efforts in vein. it aint sticky just marked.
I debadged my 156 the other day and got the majority of the adhesive off by just rubbing at it with my fingers (got a couple of blisters too d'oh). A clay bar would probably do it too. To get the last of it off, and the marks round the edge of where the badges were, I just rubbed at it with a bit of T-cut.
i did try just rubbing it with my finger an all but it didnt work and i tried with the t cut for a few minutes. tbh i just wanted to put it away in the garage before it started raining which was friday and she hasn't moved since! will try wd40 cus got that in the garage if that dont work where do i get a clay bar from? halfords? never heard on one before suppose the name gives it away what it is?
A solvent (even a drop of petrol on a paper towel) should do the trick.
Bug and Tar remover or even Scatch X both by Meguiars will also work. The latter is a product all car enthusiasts should have on the garage shelf.
Clay bars are not really meant for this kind of problem. They are used for lifting bonded contaminants from the surface of the bodywork, leaving it smooth and prepared for polishing and waxing.
BTW when finished with removing the sticker don't forget to re-wax that spot as all protection will have been removed.
General white spirit but if its a stronger glue tar and glue remover I work with vinyl all day long these two are what we use to remove the glue from vans etc I would never use thinners though i'd be too worried about taking the paint off !!
WD 40 works on some adhesives as it is white spirit based, leaves a slight oily trace, no worries though. Try solvents progressively in a hidden area first, although most thinners, solvents, will not attack modern paint finishes, but do that trial, out of vision area first?:
