Sculpey on Bondo.. Is it possible?

[Tastyburger]

I've been poking around the internet, looking for the answer to this question.

I see that bondo has been used in repairs to Sculpey, but I want to know if anyone has gone the other way around; a Bondo build finished with Sculpey.

I'd like to use the polymer clay for finish work, as it is easier, cleaner and doesn't set without being told to..

Anyone know if sculpey will adhere to a bondo'd work surface?

If Bondo adheres to Sculpey, Sculpey should adhere to Bondo.

That is true, but how's it hold up after firing? Has anyone seen any seperation issues?

I have seen separation. I have used it to fill in large cracks and also add detail on top of bondo. I noticed it only separated if I didn't give the sculpey something to grab on to. Like sanding and leaving 'teeth' in the bondo. I used a heat gun to cure the sculpey and voila! If I had the sculpey coming up on the very thin edges I'd just super glue the ends and sand. I don't do it often but that was my process.

Ok; good to know.
So, what I should take from it is that it can be done, but I should leave it for a final step only if needed.

I also forgot about heat gun curing. Putting resin in the oven is a bad idea!
