Hey guys, just wanted to throw something out there after an interesting conversation with the bloke from my paint store. He was saying that when he was on the tools before injuring his back thatthat only heat treated new plastic parts, not older ones. I was a little confused as to why one and not the other. Apparently they reckon that after time all the chemicals/release agents have already gone so for older parts they just do the usual clean, prime and paint etc.
Now mind you where I am it’s typically 30c/86f or hotter for most of the year, the main variant is the humidity. I know I’ve picked up some plastic things around the house that have been sitting in the sun and they are dam hot to to touch so this theory actually makes sense to me.
Like I said earlier, I’m just curious on your thoughts and I’m not trying to reinvent the wheel.
