Chiming in a little late here, but part of your problem is using methanol on asphalt. The methanol will react with the slurry in the asphalt and make the surface under the rubber/VHT so loose, it'll be like trying to hook in a car wash. Best bet would be to launch off of concrete. If that's not possible, use straight VHT and DO NOT burn it. Heat will turn asphalt to slime quicker than methanol. I've burnt VHT one time and it was when two 40' strips in 40* weather for a very fast 10.5 car.
For a fresh road (never raced on), do a couple burnouts on the surface before ever putting down anything. Once you get a good surface made, all you need is a little monkey **** to bring it back to life. Put a little in front of the back tires, do a burnout in the puddle (length varies depending on tire), then carry it out for a good 20'. You can test how good your racing surface is by twisting your shoe on the groove. If the rubber stays intact, it's perfect. Sticky isn't always what you look for...it's how well it stays adhered to the road.
The best thing about VHT is that it doesn't wash away with water. If it's at the end of a road with no traffic (like the spot where I tune suspension), then it'll retain it's stick for 3-4 months. VP Racing also makes a compound that I've been thinking about trying when it gets hot this summer.
As for removing it from your quarter, get some of the Gedex spray-on stuff
. On my old Mustang, I just left it on there because it looked cool.
