WD-40 on styrene?

I'm looking to use WD-40 as a barrier for putty/filler. I'm fixing a few kit parts before setting them up for casting/molding, and I want to be able to correct seams and still take the parts apart for later casting.

Has anyone tried WD-40 on styrene or in this role? I've been using vegetable oil with some success, but am looking for a cleaner alternative.

Generally, a silicone spray would be used in that role but only if absolutely necessary. I've no idea what's in WD40, and silicone rubber is too expensive for me to experiment with!

In my experience it eats plastic over time. People I've talked to who used it to lube propellers etc. found their spindles eaten up after a year or so. It's not much good for a metal preservative either as it slides off the high spots. All I use it for is rinsing metal after cleaning.

Conceivably you could use it for your project, just clean well after you're done. hth

In news: snipped-for-privacy@4ax.com, Mark Wilson bitched and moaned:

WD-40 is a petrolium based lubricant and water-proofing agent.

It would melt styrene.

I remember in my much younger days using WD-40 & 3-in-1 oil on my models & in no time, axles & shafts were breaking. If you don't want to use a silcone spray, I'd suggest Vaseline or some sort of baby oil, maybe.
