I gave up on the stick-on weights and got a variety of sizes of the clip-on weights. Re-used them again and again.A lot of them are either plastic coated or plated steel these days. I have had trouble getting them to stick sometimes - even after thoroughly cleaning the rim with solvent. I have ended out using good quality foam tape or 3M trim tape. I have some weights that clip on the center rib of the wheel. These can be re-used.
