I bought a 2014 Mercedes-Benz SLK in Fire Opal Red five months ago. There is micro blistering of the paint which is worse at low temperatures and then disappears when it is hot.The blistering looks like raindrops but feels to the touch like an attack of measles just below the paint. I have read this defect is not uncommon on red Mercedes manufactured between 2011 and 2015 and some people have reported continuing problems even after a full bare body respray. Do Mercedes have a solution to the problem or will a respray only make it worse? Do I have the right to reject the car while it is under the dealer 6 month warranty or am I better off claiming from Mercedes under their 3 year warranty and paintwork warranty. Will the micro blistering get worse over time or will it improve once the car is hot over the summer ?
