Can I contact 3M for parts to service my DMS? It's been amazing for years but it stopped working and I just got it back out of storage to see if I can get it going again.

What is preferable for tip cleaning if you have some leakage, as you talked about near the end? MEK, Thinner, Acetone just curious as this gun has to last a long time. I hope techs are using filtered clean air for gun use although I have not bought one, I have not seen instructions on use or clean up. Thanks.

How much does the gun cost? I am courious to try the body filler, I know it’s hard to say because some suppliers sell it for more than others. But around how much?
