One of the long list of brilliant things I’ve picked up from Paul is this product for nearly all dope thinning needs. It’s like $16 a gallon at Home Depot
I’ve been using Klean Strip lacquer thinner for years. I would point out, that you want to use the high VOC thinner. The low VOC stuff turns to snot when mixed with dope.
I would also add that the Klean Strip thinner drys fast and will blush in high humidity. So be sure to have some retarder handy.
