Practical Buying Advice:

Choosing the right spray can auto primer depends on your project’s scope and your skill level. For small touch-ups, a spray can primer like PaintScratch is a good choice. For larger projects, you may consider a higher-volume option or a 1K primer and a spray gun for more professional results. Remember to always clean the surface thoroughly with a degreaser before applying any primer.

FAQ:

Q: Do I need to sand after applying primer? Some primers are sanding primers; others, like the Custom Shop 1K, are non-sanding. Check the product description carefully.

Q: How many coats of primer should I apply? Usually two thin coats are sufficient, allowing each coat to dry according to the manufacturer’s instructions.

Q: What type of spray gun is best for automotive primers? HVLP (High Volume Low Pressure) spray guns offer good control and even coverage.

Q: Can I use any type of topcoat over the primer? Check the primer’s compatibility with your chosen topcoat. The product descriptions should list compatible topcoats.

Q: How long should I wait between coats of primer? Follow the manufacturer’s instructions for drying times between coats. Rushing the process could lead to an uneven finish.

Q: What should I do if my primer looks uneven after application? Lightly sand the surface with fine-grit sandpaper, then apply another thin coat.
