Topcoat application
Topcoats and clears must be elastified by adding 25% Glasurit 522-111 Softface Additive before being applied to for example PP-EPDM, PA, PPO.
Topcoats and clears must be elastified by adding 50% 522-111 Glasurit® Softface Additive before being applied to soft PU foam.
Basecoat plus Clearcoat
Step 1: Cleaning of sanded Primer filler
700-1
Wipe dry
Step 2: Application of Basecoat 90 Line
90 Line
2:1 with 93-E3
Standard pressure setting
HVLP 1.3 with 2 bar
First spraycoat:
1 normal coat
Flash-off until the surface is uniformly mat
Second spraycoat:
1 full coat
Flash-off until the surface is uniformly mat
Third spraycoat:
1 effect coat / half spraycoat
Flash-off until the surface is uniformly mat
We recommend forcing the flash-off process of the basecoat with suitable venturi systems. First and second spraycoat: Distance between the spray gun and the object 10–15 cm. Third spray coat: Distance between the spray gun and the object 25–30 cm.

2:1 + 10% with 929-33 + 352-91
Standard pressure setting:
HVLP 1.3 with 2 bar
2 spraycoats with ~3 min. flash-off time between coats
Apply the first full spraycoat of the clearcoat from a distance of 15-20 cm, and after 1-5 min. flash-off apply the second full spraycoat from a distance of 15-20 cm (film thickness of approx. 50 µm).
Step 4: Immediately after application, the product can be dried without additonal flash-off time

CCC - Artificial aging
The approach of preserving as much historic substance as possible to retain the vehicle’s identify calls for spray painters to change some parts of their mind-set when refinishing classic cars. Today’s paint materials make it possible in many cases to precisely match the old appearance.
Cosmetic Repair
The is a fast repair solution for minor damage such as stone chips and small scratches.
The repair process is performed without a spray gun and the result is called a “cosmetic” repair. The goal of these cosmetic repairs is to repair minor paint damage so that it is not directly visible from a distance of 1,5 meter and that it is prevented from spreading due to penetration of humidity or corrosion.
