I bought a few of ^^^^ rails, here is the trick. First clean the rail with laquer thinner, allow to dry to ensure it is 100% clean, then wipe the rail again but fore the rail is 100% dry put the strip on. What happens is the laquer thinner will slightly disolve the adheasive, but once it flashes off the glue will reactive at full strengh. By using this procedure you can re-use the splinter strips a few times over, in fact I am using the 3000mm rails strip from the previous owner. JAvais could vslidate how the strips were falling off the 3000mm rail.
