Plastic welding

[lord_deastofact]

I am wondering if anyone on here has any experience with this. I need to modify a few parts and plastic welding looks to be the way to go and there are a few different options to go with on welders but I am curious if anyone on here has done this before and has any pointers?

What are you looking to do?

I used it to fix my dash in my old car when some bitch stole my radio and broke the dash up. It worked pretty well.

a good thing to do if it is a crack is groove out the crack and melt/fill it with plastic filler rod. least thats how i do it on bumpers when I weld them....

Well I was trying to modify some parts on my sled since I dropped a different engine in and the oil box was not fitting. I wound up modify the airbox and plastic welding it. But it worked like shit. I could not find a rod that would bond with the material it was made out of. I wound up using slices of the box as weld. I am not sure if it was something I was doing wrong or not but I have to also try to do it for my intakes so I guess I will get more practice. So far I am not impressed though. I could have got the same results with a propane torch.

have you ever looked into any of the adhesives they use in autobody. 3m, lord fusor, evercoat and valvoline all make really good products. probly the best would be the evercoat since that one dont take a special gun, just a typical calking gun is all you need.
