My only advice..... Don't go nuts with it....
on a bash car u won't notice much of a difference, but on a track car u will feel a slight reduction on preformance. Especially on vehicles with a poor COG.
over here in Australia I'm paying $15 for a tube... And I've found a open tube only lasts 6 months before the glue becomes less tacky to the point it's very hard to get it to stick.
so in some cases like 1/10 touring cars, sometimes they can be cheap enought to buy rather than trying to fix.
