This body filler is AMAZING! I am IMPRESSED! Look what I did with it!

I am a handy car guy. I build hot rods. I restore cars. I fix things.(This really does relate to body work. Read on to see just how awesome flexible body filler really is!)As a car guy, I think of products in the automotive field for many other projects. Not for their original intended use.I am a huge Ghostbusters fan. I am planning on joining a GB club that raises money for charity. They raise money for children's hospitals and such. So, I need all of the GB gear.I bought an expensive Proton Pack for a great deal. This particular pack has a problem, so most enthusiasts won't buy this pack. The problem is that the bumper bar is molded into the pack itself.See that first photo? It shows where I cut that bumper bar off. Which leads to photo #2. I had a huge gap to fill. Well, this particular pack is made of a flexible material. It's like a heavy thick flexible vinyl. As a result, I couldn't use plain old body filler. After doing some searching I found U-POL 7061. It is exactly what I needed. Flexible strong filler.In pic #2 you can see that I used traditional flexible adhesive aluminum body filler backing. In pic #3 you can see a thick layer of the 7061 filler. This was just like doing auto body work. Application was just like using plain old filler. I used my pneumatic DA sander for the rest of the shaping and finish work.I ONLY used this 7061 filler. No other fillers or products. It is really easy to work with. I used filler primer, followed by flat black spray paint followed by a light coat of bed liner.Pics #4 and #5 show the end results. Looks great, right?The last pic shows the final result. If you happen to be a nerdy car guy who is in to Ghostbusters, you would appreciate just how awesome this Proton Pack is now!I am VERY HAPPY with the end results. This thing is rock SOLID! It looks GREAT!This will be my go to filler if and when I need to repair any flexible panels / bumpers on any of my vehicles.As you can see, it can be used for some unconventional projects as well.This filler may be a little expensive, but I could not have done this project without it. It was well worth it!

Work great on older plastic body work.

Very easy to use like regular body filler. The dark color makes it a little difficult to tell visually if you have a good mix after adding the hardener. Sands pretty easy and the edges seem to feather in nicely. Just make sure you clean well with denatured alcohol or some other wax/oil remover and scuff the surface slightly before applying.

Very workable, flexible and strong.

This was my second tupb, and I'm about to order another. So far, I have patched two bumpers (a couple of big gashes) and reworked an interior trim piece. I love how sandable this filler is, and it will sand very smooth for a nice painted finish.

Awesome product

Had some deep gouges in my vintage atv plastics. Replacements don't exist so i was trying all sorts of products. After many wasted hours with 2 part epoxies and shortstrand fillers i stumbled across this product. To my amazement it worked fantastically. Feathered out easily and builds quickly and evenly.

2 year old product still works

I received product that is 2 months away from the 2 year expiration date, which is a "Richard" move in this industry. However, the stuff seemed to work just fine. I applied it to a plastic bumper that I am refinishing. It spreads great, and is fairly easy to work with for what it is. I noticed a booger of 706 had accidentally dried on one of the "fin" features that run down the centerline of the bumper, which was hard to reach with sandpaper. I pried the dried glob off with a razor, and noticed that it took the paint off with it, indicating good adhesion.Besides the seller sending me 2 year old product, the other problem with this U-POL 706 is the super deep lid. Of all the cans of stinky product I've pried opened, this lid design is the worst. The lid is so deep, when you pry on one side, the other side sinks back down and re-seats, and vice versa. All the time, you're fighting the suction of the goo inside. After resorting to pliers to rip the silly lid off, the lid no longer fits into the deep draw so nicely, and I suppose the magic which makes the 706 work will soon escape. Also, the instructions (not included) found online are not very detailed, and contain cryptic "paint society" codes that are dubious at best to amateurs like me.For $50, I expected fresh product, and an seriously frustrating-free lid. In the end, it did the job very well. After wet sanding down the filled areas with 400 grit, and spotting the pinholes with glazing putty, the areas patched with the 706 were ready for primer.

Works as it should

Great for plastic bumper repair. Easy to sand and feather.Somewhat pricey but you get quite a bit so it will last a long time

Okay but not great

Adhesion to SMC and plastic is tops. However, pinholes are awful with this body-filler and yes, I know how to mix and apply filler. Been doing it for 20 years and I'm platinum ICAR certified.The spreading is easy with decent fill but the sanding is just okay. It reminds me of an improved Kitty Hair. So, don't think you can "spot-In" your filler. You're best to re-coat entire are to sand flat.

Fresh product produced just 5 months ago

Nice fresh product seems to work just as advertised. Just received the product yesterday and, while I did use it today, it's a little early to tell how it will work but all is well so far.
