The Red First Contact Combo Assortment kit is a good choice for customers requiring both spray and non-spray formula polymer such as for testing / evaluation, cleaning a 12" telescope mirror to include the secondary, etc.
If you are cleaning a SCT Corrector plate the best kit choice is either our Red First Contact Regular All-Inclusive kit or our Red First Contact Deluxe All-Inclusive kit. This all-inclusive combo kit contains primarily SPRAY formula polymer. Corrector plates are better suited for NON-SPRAY polymer.
This kit contains sufficient SPRAY polymer to cover up to 160 square inches and NON-SPRAY polymer to cover up to 60 square inches, and required application and removal accessories.
For mounted optics we suggest purchasing our chemically inert mesh (FCNet) for easier film removal. Eyepieces and objectives demand FCNet or FCUF unwaxed dental floss.
