Had a few french car park dinks on one side of my Dethleffs MH and decided to have a fresh decal to cover up the damage...Silk purse out of Sows ear i hear you chant!! Thought Dafne deserved a facelift so went on a" pimp my motor" decal frenzy and now needed to remove ALL of them ..a total area of 3 sq. mtr. Spent a day using girlfriends hair dryer ,pecking away a decal area of 8x6 inches..Nightmare!! Needed a different approach..heres what i did.. utilised Screwfix Titan hot air blower with blade nozzle attachment which easily lifted the decal and separated it from adhesive, but care is required on heat setting (alternate between level 1 and 2) and ensure quick movement is maintained to reduce heat buildup on MH material. This approach removed 95% of decal area in 4/5 hours. Purchased Rubber Stripe Off disc and plastic razor blades from Amazon. The rubber disc removed remaining decal material, had to use mains drill for stripe disc as battery drill did not have enough grunt .. need about 3ooo RPM , anticlockwise application seemed to work best. Application of Tar and adhesive remover from local motor factors ( 5 litre @ 13 .50.. use gloves!) with plastic razor blades removed bulk of adhesive. Residue of adhesive removed with rag and adhesive remover...Job done...now gonna have new all grey decals fitted..
