A bit late for this post, but for anyone still looking...….my experience is that getting a colour match is near impossible, that said, the texture match is relatively easy. I use neat SBR on the patch and especially the edges and rub back very gently. If you are looking for an invisible repair, get ready to shell out on K Rend Colour Enhance paint. I understand that Weather Shield works well although I have never used it myself and could not comment on colour matching. I am always open to further advice, every day is a school day!
