This is the first time this has happened to me and I've done nothing different in the prep!
I rubbed down a cold, previously painted radiator (satin white) that was in good nick - just tired. I painted it with two coats of Crown white gloss - not sure if it was non drip/ solvent based/ water based - does it matter? Looked good until the radiator was switched on and now it is yellow within two weeks of use!!! Good job it's behind the bed - I am not a happy chappy (female actually).
I have read the posting to dave57 Dec 09 2010 from the shedman. Anyone in agreement/ have other ideas?
Thoroughly annoyed. :x
