Heavy Tar

I've googled "heavy tar" and "JB Heavy Tar" with no worthwhile results.  Can someone give me information on how to find this stuff that CDT referred to in his 'All about lubricants" page.  I want to try some on a Fast Deer spring.  Thanks in advance.

Here's the link to the website.

You will do better on the Fast Deer with just a little Molly Grease. "A little gors a long way" Cut it about 3 to1 with Corn Oil Cooking Oil.:p :p

see you back. I was wondering the other day what happened to you

....you're likely to lose some velocity, especially with a moderately powered gun like the FD.

I had been out of comission for a while, but I'm feeling great lately. No pain. It's been about 6 weeks now that I've felt good. I'm getting back into airgunning 100% now. Everytime this happens, I feel I've been given a second chance. Anyway, sure feels great. I've been shooting an aweful lot lately and trying to get on the forums when I can.

Thanks Charlie...

Thanks guys.  My observation from tuning 6 Fast Deers for family members is that the lower velocity guns are more accurate at the 13 yard distance.  I've got one that really pops when fired... like it is much higher velocity than the others.  I was thinking some heavy tar might quiet/slow it down to more accuracy.  It also occurrred to me that by leaving it cocked for an extended period of time might weaken the spring and lower the velocity also.  Am I alone in thinking that as a general rule when velocity goes up the accuracy goes down in springers?  I realize that there are exceptions to this rule and there are airguns that shoot higher velocities and are also accurate.  But I haven's seen to many exceptions.  Your thoughts?

More power usualy means more "recoil",so the consistency of how you hold the gun becomes more critical.This can be offset by adding weight to the gun,to some extent.Try to keep the added weight as close to the centerline of the piston as you can.Another factor is that often,especialy with the chinese guns,a hot one is dieseling more,which tends to cause a wider range of velocities than a gun dieseling less.On the other side,a faster pellet will drop less and be blown around less.
