E. Touching-up Paint that is resistant to Skydrol
(1) Preparation of the areas to be painted
(a)
Clean the surfaces to be painted with CLEANING AGENTS (Material No. 11-002). Dry them with clean, filtered compressed air.
(b)
Apply the STRIPPERS (Material No. 12-005) with a paint brush. If it is necessary, use a brush on the surface.
(c)
If you do this operation in a building, make sure that the work area is open to the air.
(d)
Do not let the material touch the surfaces for more than 5 hours. CAUTION : THE MATERIAL MUST NOT TOUCH RUBBER, PLASTICS OR
_______
ASSEMBLY AREAS.
