Hempel’s range of Hard Racing products are especially suitable for powerboats, racing yachts, vessels moored in mud berths and boats that are dry sailed. The hard nature of the matrix makes it resistant to the increased abrasion that is incurred in these situations. Hard Racing can be burnished by sanding (240-600) to give a very smooth surface which is especially good for racing yachts. Suitable for all substrates - check recommended priming system for your substrate. Check maximum launch time of the particular Hard Racing product you are using.
