Stripspeed has been developed to remove Propspeed easily and safely from propellors and metal surfaces. No need for grinding or harsh abrasives that produce toxic airborne dust and debris. Simply paint the thick Stripspeed onto the metal, wait 20-30 minutes and then scrape off into a drop sheet. Wash away remaining residue with water and a rag. Any hard to remove etching primer spots can be removed using a Propclean wipe that comes in the Propspeed kits.
