The most common type of paint finish on modern mass-produced cars is:
Low bake enamel
Cellulose lacquer
Tinted clearcoat
Water-borne COB
To determine if a substrate to be repaired is finished in 1k or 2k materials:
Use compound and look for discolouration of the finish
Sand with 1500 grade paper and look for clogging
Do a solvent wipe test to see if product is removed
Do a fingernail test to see if surface scratches easily
To identify a steel panel prior to preparing ready for painting:
Look for label description
Scratch the surface
Tap it with a hammer
Check with a magnet
When preparing an unprimed plastic bumper for painting, which one of the following should be used?
1k cellulose primer
Wash etch primer 3
High build 2k primer
Adhesion Promoter
When painting a soft plastic component that has been primed ready for colour, the refinisher should:
Use a slow thinner in the topcoat
Bake at higher temperature
Add flexible agent to the top/clear coat
Use extra hardener in the topcoat
Product description and application methods can always be obtained from:
Phoning the supplier
Process data sheets
Product container
Searching the internet
The correct application viscosity of refinish products is important to ensure:
There is enough material to finish the job
Maximum performance from the material
Absence of dirt inclusion in the paint film
Thicker coats for higher film build
In order to check and adjust the consistency of a paint mixture:
Add more hardener if material looks too thin
Add a smaller amount of thinner on a warm day
Add thinner until material runs off the stick freely
A specific standard viscosity cup has to be used
When using a 2k stopper the activator is mixed in:
15 minutes prior to the application of mixture
Prior to use, but left to stand for 5 minutes
10 minutes before use to ensure total mixing
Just prior to use, then applied immediately
What will be the likely result of baking a repair after applying a high film build of 1k stopper?
A high gloss spot will appear above the stoppered area
The overall quality and appearance of repair will improve
The stopper will become too hard to shape by wet flatting
Topcoat will be drawn into the stopper creating mapping effect
Which of the following procedures should be followed when mixing 2k undercoats and primers?
Measure primer and hardener then add thinner to stabilise the mixture
Measure primer, hardener and thinner in tapered cup with a stick then stir
Pour primer, then thinner, then hardener into container and allow to stand
Measure primer, activator and thinner with a ratio stick in a straight-sided cup
