Here is a tip.
Do it right.
The only people using gilsonite around here are the fly by nighters. Its NOT a sealcoat. Its a colorant.
It goes 10-15 times as far as a sealcoat. Hence why all the gypsies have those little tanks hidden under tonneau covers. One gallon covers A LOT of ground.
I would have to see pics of your sprayer to tell you why its not spraying right.
Youre going through an awful lot of money and trouble to put something down that will be gone in a couple months.
A lot of guys knock the "trash pump and tote" setup but it works. Thats what I started with. It will spray real sealer with a light sand load.
Get some real sealer. Spray your drive. And you'll be good to go for a few years
