TTWAGN, I'll have to pick some 86 up and give it a try. You might want to try M95, as well. It's a traditional compound, but it finishes down so very well. It seems to be much more consistent than 105 on it's ability to leave a very, very nice finish for a compound. Not LSP ready, but *very* often hologram and trail free. Great stuff. Megs is really putting out some great stuff nowadays.
105 is kinda losing it's appeal to me. I can't get it to consistently finish off well enough to go straight to a finishing polish. Much of the time saving from using 105 is not being realized, since an interim polish of SIP is sometimes needed before going to the finishing polish.
*So far* (and I haven't used it enough yet to know if this is the rule or exception), I've been able to get 95 to finish off well enough to go straight to final polishing. M95 takes a bit longer per application than 105, but saving the middle step more than makes up for it. 95 seems to finish darn near as well as SIP on the cars I've used it on so far.
