What can I use for epoxy fairing/filling that can be sanded in <1 hour?

[wet feet]

Thanks! I'll see if I can get it shipped here fast enough. If not, how do I determine the type of powder used in a particular filler? I can't see it in my datasheet for that Chameleon filler, nor any others that I can source locally.



You mean to say that regular epoxy primer wouldn't work? I need some kind of special primer? Again, did you determine this from the datasheet somehow? Maybe I'm missing something obvious in there :/ I assume you meant that in contrast P38 can be painted directly on, without primer?

The Chameleon Data Sheet has a section headed ATTENTION and the second bullet point says "Do not overcoat with topcoats without having isolated the surface with Chamäleon 1K or 2K primer." .Now I do get a bit cynical about companies insisting that only their product will work for a particular job and would ordinarily suggest running your own tests to determine the accuracy of the information.However in a situation where time is pressing,I wouldn't run the risk of things going wrong.I don't know of a filler that has the precise chemical composition of the powder stated on the container or in the documentation as it might be giving useful information to the competing businesses.

I can assure you that P38-should you be able to get any-will work with shellac,oil based paints,2 component paints and epoxy coatings.

I have had slow epoxy kick in 15 minutes and be garbage in 17. All depends on temperature.
