Articles such as medical devices are selectively coated with a lubricious coating. A temporary coating, formed from an aqueous solution of a water-soluble polymer of low to moderate molecular weight, is painted onto those portions of the article which are to remain free of any coating in the final product. Then, the entire article is coated with a material which forms a lubricious coating. The article is then soaked in water to loosen the coatings at the locations at which the temporary coating was applied. The coatings are cleanly removed from those locations, leaving an article with a lubricious coating in some portions, and which is uncoated in the remaining portions. The process can be used in coating portions of catheters, surgical gloves, contact lenses, and any other articles which require a lubricious coating only on a portion of the surface of the article.
