yeah, thats what you want to use. My best advice is to apply it to the area needed and shape it as best as possible. The warmer the outside temperature is, the faster this stuff drys, so if your doing this in a cold garage it may take awhile. Anyways, whenever ive used this stuff, i usally dont wait for it to cure completely. Wait for it to get pretty hard, but somewhat soft enough to where its easy to sand to the desired shape. Sometimes it may take 2-3 applications to get the desired shape you want.
