Dupli-Color FP101 Scratch Filler Primer, Gray – 11 oz. Aerosol Can

I can't say enough good things about this Dupli-Color filler! It works as both a sandable filler and a primer, making it extremely convenient. I use it all the time, and one of my favorite things is that it dries completely within an hour or less, and you can wet sand it if needed. It also does a fantastic job of filling in gaps without clumping. Overall, it's a great product.

This is definitely really nice quality primer. Nozzle was an absolute dream, sprayed well and not tiring, and the primer is good quality. Went on well, dried well, and smoothed down well. Used it for a guitar.

On red of my go to items

Unfortunately, the can of primer I received had a defective valve. When the spray button was released, the paint would continue to spray for a second or two and sputter.Worked around the problem but would like the product better if the spray valve had functioned properly.Will try another can to see if the sticky valve is not the normal operation.Dried quickly and leveled out very nice and even. Was just able to get 2 coats on about 6 or 7 square feet of surface.Very easy to sand with no clumping.If the next cans spray valve works as it should, I would recommend! 👍

Quick delivery. Worked as advertised

Pros: goes on easy, sands well and cleans up very nicely. Works great and has a nice smooth finishCons: Cost a little more than the cheap stuff but worth itThis is my goto stuff for 3d prints. They often have layer lines or imperfections and this covers them well and really easy to sand. I use WAY less sandpaper than with the cheap stuff which alone is worth it.

Use this for 3d prints. It is by far the best filler primer I've used and I have used many. It goes on so light but fills things perfectly. I even put extra spray over areas that need a little more and it refuses to be runny it just sticks. If you're trying to fill something just get this.

When you read filler primer, you think thick heavy coats. Its sandable as well, for sure you think blocking & shaping panel. Filler Primer = 2 steps in 1, or at very least it'll fill pin holes, minor scratches, and any tiny imperfections. I believe I burned through all 4 cans I had ordered to cover entire front bumper, and still ended up with light spots in places. I tried wet sanding and in random spots, as soon as water contacted surface, primer became very thin almost translucent, as if it were water based. I gave it the directed flash time before sanding, and it was only sporadic spots. Also applied adhesion promoter generously prior to primer. I was satisfied with end result, just had not planned on using 4 cans just on front bumper. Another dislike was the splatter that would occur once can was close to empty.. ~25% paint left and also does not spray at any angle after first 15-20% is used. Hand ended up cramping up from finger fatigue having sprayed 4 cans. I do like the shade of gray, it almost matches base paint on car, brilliant silver metallic. Depending on project and expected results, it is a decent budget primer, as such you may need to double your application/quantity to get a filled look
