I'm going to use AutoGylm Super Resin Polish on my car, and then Autoglym extra gloss protection. (I put some extra protection on yesterday, and it leaves a tough coat! I had a small watermark on the paintwork from washing, and it is now under the protective layer and wont buff out easily!! lol
I need to polish that out and then use the protection again.
The extra gloss protection is easy to do. You wipe it on without pressure to leave a wet coat, then after an hour, just buff it off for a mirror finish. (Just make sure the bodywork is free of water marks etc....)
So for a small scratch, I think Super Resin Polish, then the Extra Gloss Protection. (Amazon had the best prices)
