Good patching compound

I bought this to patch some siding. It applies easily with putty knife or finger, sands quickly, and takes paint well.

Great exterior multiple-applications spackle!!

Would Recommend

Using product to restore T1-11 sheathing on my shed. It adheres very well and fills "bumps" and voids; its weather resistance is outstanding; sands easily to a smooth (paintable) surface. I also used product as body filler on my (white Subaru Forester) SUV to repair dents and scrapes (from a scrape incident with my garage bay pillar)

Easy on!

Would Recommend

Was easy to put on, and able to sand it down, so it could better blend in with the surrounding siding.

Very hard once dry

Would Recommend

I have not used before. But this compound was recommended for patching exterior vinyl trim. It is surprisingly hard. It was a bit sandy, or gritty but sanded out for primer then paint. I will use for other handy patching jobs. Ken

Boat work

Would Recommend

I used it to fill small gaps in my boat I was redoing. Mostly to cover screw holes and to fill seams on a center console I was building for the boat. It dried fast, was easy to sand and was easy to fiberglass over. Definitely worth the money if you need to for small work.
