Air bubbles on surface of skin, what to do?

[medium_tea]

I attempted to repair skin abrasion using a hot soldering iron by waving it over the TPE, the TPE melted together, but unfortunately now the skin looks like it has many bubbles in it i.e. not smooth.

Should I try using a small heat gun to airbrush the surface? I remember a similar technique before, but cannot find anyone actively using this method.
I also tried chemical smoothing, but it sometimes eats into the hole making it deeper.

Thank you.

Mishka posted a video recently that covers this sort of thing. He used a heat gun and then smoothed the tpe with a piece of cloth soaked in baby oil. You need to clean the surface well first with baby oil prior to applying any heat. I've done it myself and it works well for small cuts and abrasions. I used a hot air rework station rather than a heat gun but the process is the same.

Air pockets and bubbles.
Too much baby oil used??
Too hot?
tiny bits of dirt and debris can cause air bubbles too. I'm always cursing TPE and it's dirt magnet characteristics!

keeping tools and the area super clean is extremely important.

Shoot a pic for us, if they're like little craters, you can always fill them in with spare TPE

Thank you for the replies.

Well it is less of "bubbles" than simply me waving the soldering iron unevenly over the skin, so there are some small indentations no larger than the tip of a toothpick but there are many because it is repair from abrasion.

Anyway I found Mishka's post on heat guns, thanks.

Plug Plug...
I have videos on what not do, and a successful major repair on my dolls foot.
Soldering iron as well as heat gun fun...
Just finished her foot last night.

Here it is...
