It is vitally important that you use a product designed specifically for the fabric of your microlight - and this is just the job! It is highly recommended that you wash your fabric with this solution before applying the 303 Aerospace Protectant.
Also, If you are likely to be storing the Microlight in a damp environment (like a farmyard, shed etc you should also sterilise the fabric before using the 303 Aerospace Protectant).
