Stringed Instrument Aerosol is specially formulated as a high quality finish for thin, flexible tone-woods such as those used on 
stringed instruments, made to withstand the expansion and contraction that is characteristic of the unique construction of 
stringed instruments. 

Vinyl Sealer is also flexible, therefore it is the only sealer that should be used under Stringed Instrument Lacquer.
These two products together provide great sound and enables luthiers to finish their projects with confidence.
