FAQ > Gelcoat Blooming/Discolouration

This answer was provided by Ian Cummings (BEng Polymer Technologies) via the SmartGroup

Why has the gel coat on my kit car bloomed?

Any polish containing ammonia is not good for Polyester (gel coat) and will eventually cause the resin to break down. This gives the blooming effect in the gel coat. A good polish to use and one that Quantum Sports Cars recommend is Autoglym, which is an easy to use polish and does not contain ammonia.
