HOW TO AVOID

Adapt material, spray gun and spraying technique to application conditions in the workshop. If necessary, clean spray gun and use a smaller nozzle.

REPAIR

When the paint is completely dry, remove the run with a sanding block, carbon block or wet sanding paper. The finer the paper, the less damage to the paint and the easier to polish. Polish with Glasurit 562-1602 Fine Polishing Compound and finish with any standard high-gloss polish.
