REPAIR STEPS:


1. Move vehicle out of direct sunlight and allow paint surfaces to cool if necessary. Dark painted colors become warmer in direct sunlight and require a longer period to cool off.

2. With vehicle surfaces cool, wash with automotive liquid soap & water.

3. Neutralize any remaining acid with solution containing 1 tsp. of baking soda per quart of water (solution may be evenly applied using a commercial grade plastic garden sprayer).


4. Take accurate measurements of paint film thickness in several locations on an affected body panel (decklid is recommended due to consistent surface flatness). Record measurement on a short piece of masking tape attached to panel area adjacent to measurement area prior to buffing.

Caution: To minimize the possibility of burning through or hazing paint surfaces, the following buffing procedures should be performed only by personnel experienced in rotary power buffing.

5. Buff the affected areas. Regardless of system preference, it is essential that all repairs begin by using the least aggressive pads and liquid compounds. Remember to periodically measure the paint film thickness during the buffing process. Either system should provide desired repair results (on Minor acid rain damaged vehicles) within a short period of time (approximately 30 minutes per vehicle).

^ Using 3M's "Finesse-it II"system, begin with a "yellow" wool buffing pad
(less aggressive than the 3M's "white" wool pad which is also available).

^ Meguiar's equivalent "Finesse" system utilizes a combination of # 2 & # 9 liquid compounds with yellow (less aggressive) or pink (more aggressive) buffing/polishing pads and white pad (least aggressive for final polishing).

Note: Meguiar's # 1 and # 3 liquid compound system is more aggressive and can be subsequently used with care if increased abrasive action is desired.

^ Very lightly affected areas may alternatively be buffed using 3M's recently introduced "Perfect-it" system which utilizes a single buffing/polishing pad similar to Meguiar's white foam pad, in conjunction with appropriate designated compounds.
