I have been in body and paint for over 30 years. This is by far the best plastic filler I have ever used. I have spent huge money on supposidly better fillers. You can now quit wasting money like I did and buy and try this product! It is very creamy and mixes very well. It sands like nothing I have ever used. It will not clog up sandpaper like every other brand I've used over the years. Never any pinholes or bad spots.
