I have not removed my racing stripes yet. I went to a Carquest body supply shop and they had several spray cans of decal remover - I got the 3M brand - much nastier than WD40 I'm sure - it calls for masking off the area to be treated, wearing hand protection and lots of fresh air. When it warms up...... I also obtained a couple of Mercedes "TURBO DIESEL" emblems which will install where the Isuzu Trooper decals are high on the rear quarter panels
