Hi
The molding tape I've used with great success is 3M # 3615 Super High strength molding tape , its about $7 a roll.
The key to all this is cleanliness of the part and the attaching surface. You can use a sharp putty knife to get the old adhesive off after you soften it with a pre-paint pre-cleaner such as Ditzler/PPG DX330 or if you can get it plain old Lacquer Thinner. I prefere the Lacquer Thinner. Alcohol is useless and the WD-40 is also a waste of time as its neither a lubricant or a penetrant
it was created as a water displacement solvent (Now you know what WD means). All I use it on is locks in the winter.
Anyhow once the surface is free of the old adhesive clean it again with a fresh rag and the pre-cleaner to ensure no oil ,silcone or wax remains on the surface. Clean the back of the molding(s) as well. Apply the tape to the molding first , peel off the backing and attach to car. Hope this helps!
