I, in another moment of stupidity, mixed up a batch of Bondo to repair some small holes in my spoiler. I used way too little hardener. Now most of the filler is soft. I need to get it off. I used a very duty power washer at work to little avail. That stuff stays in place. Do you suppose if I mix another batch with an abundace of harderner, the 2 applications will bond? If not, how do I get this stuff off? "DOH"
Yep scrape it off as much as possible. Any bondo that does not have enough hardner will most likely not harden. Whatch for the color change of the bondo when mixing!
Scrape off what you can, and remove the rest with lacquer thinner and some old rags. If it hasnt hardened...The lacquer thinner will cut it so you can remove it. Let the work area dry completely. Sand area and re-apply properly mixed filler...Good luck!!!
