Many people have had problems in the past getting blazers to stick to a bare shaft. Some said it was the glue, some said the shaft and others said the problem was with the vanes themselves.

That being said I have never had adhesion problems with my blazers, however I always use a wrap on the arrow. The wrap bond to the arrow very well and the Bohning Platinum bonds the blazer to the wrap.....forever. The only fletches I have lost, took part of the wrap with them when they were torn off.
