Hylomar Aerograde PL32 is the product which should be used by all aircraft manufacturers which conforms to the original Rolls-Royce specification. Aerograde Ultra is a Rolls- Royce specified product which uses a different solvent (acetone) than Aerograde (methylene chloride). Universal Blue is the original non-setting sealant used for all non aircraft applications. Racing Formula is a new non-setting sealant developed using a different solvent system to Universal Blue. Advanced Formulation is a non solvented non setting jointing compound.
