A highlight grinding-free gel coat is prepared from, by weight, 100 parts of matrix resin, 2-3 parts of thixotropic agent, 0.1-0.5 part of dispersion agent, 0.3-1.5 parts of surface auxiliary, 0.2-0.6 part of thixotropic synergist, 5-10 parts of filler, 1-10 parts of mill base, 0.5-2 parts of low shrinkage agent, 0.2-1 part of accelerant, 20-30 parts of styrene and 1-5 parts of acetone. The prepared highlight grinding-free gel coat mainly has the advantages that matrix resin high in exothermic peak is selected, so that the gel coat has high hardness after being cured, and a high-gloss surface effect is generated more easily; by adding the low shrinkage agent, contraction of the gel coat in the curing process is reduced, the gel coat is flat and smooth after demoulding, the finish degree is good after slight polishing, and the grinding procedure can be omitted; a gel coat mixture is ground to certain fineness by means of a grinding machine, so that the surface of the product looks finer and smoother.
