I've recently gotten a stress mark on my MP Skywarp on the nosecone I remember reading around that using a blow dryer gets rid of stress marks and I tried but no dice. Is there any way to get rid of them?
A hair dryer has always worked for me. If you have any bubbles from open toys that you don't care about, crease them until you get a white mark then try the dryer. You'll get the idea of what it takes. Just be careful not to overdo it. You can't fix melted.
Heat it extremely slowly, and don't make it any hotter than you have to. Underheating shouldn't make things worse, so its better to err on the side of caution and do it a couple times than it is to overheat it and cause heat damage. Different plastics are going to react differently, so there's no real way of telling how long it'll take unless someone has done this exact piece before. Make sure you watch the other parts as well though, they might have lower tolerances for heat than the nosecose.
I always pass the mark above an open flame, like a lighter or a candle. Works great - just don't set it on fire.
This is the first time I've heard of anything like this. So if you do this properly (using blow dryer, open flame, etc.), you can restore the integrity of the plastic?
Exactly. If anything, you're -minutely- decreasing the plastic's integrity. It's strictly a cosmetic fix.
It's like putting a paper bag over an ugly woman's head. There's still problems underneath but you'll feel better about it because you can't see them anymore. I've tried the blowdryer trick a couple of times and it's worked out okay.
Not very long. Move the dryer around a little while you do it so you gradually warm the whole area. This works to fix some dents and bends in the bubbles too. The warm plastic tends to work its way back into the molded shape.
