Bodywork questions?

I have had a few people ask me about mising paint and spraying panels, so heres a quick guide.  Some is lifted from another site but thats just to save time.  I normally follow these guides when spraying panels

Thinning for different types of paint products requires different amounts. The general rule of thumb with solvent based paint products is as follows:

1. Etch Primer = 1:1 ratio (1 part paint to 1 part thinner)
2. Primer = 2:1:1 ratio (2 parts paint to 1 part hardener & 1 part thinner)
3. Base Coat = 1:1 ratio (1 part paint to 1 part thinner)
4. Clear coat = 2:1:10% ratio (2 parts paint to 1 part hardener and then add 10% of thinner).

Please note: These are fairly generic ratios. As a customer, you should ask the paint supplier for a technical data sheet for all the types of paint being used, as they carry all of the information required to use these materials i.e. pressure/temp/air-cap/nozzle size, etc.

Bearing in mind that i normally use a low pressure compressor, this is due to doign targetted repair or small areas, i throw it on at 30psi with an even air mix.  I would use the same ratios on a high pressure gun if doing a full shell but the key is preparation.

hope this helps someone
