First time painter shoping list?

First thing on the list if you are serious painting and resto. Organic Vapor respirator.

Then....

Air supply. 2 Stage with minimum 14-16 cfm @ 90 psi.

Good air filtration. Motorguard setup is great.

HVLP gun for priming. I like Devilbiss finishline3 1.8 and 2.2 tip set cupped.

For base,clear, and all other automotive paints and sealers buy an RP or compliant gun with a 1.3 or 1.4 tip. I like Sata but a Devilbiss GFG Plus Gum or Teckna Copper (7E7 cap) is fine.

Don't skimp on this list above and your experience will be much less frustrating.

Use only 2K primers and paint. Anything that uses activator, hardener, or catalyst are all 2K.

Passover the enamels and stick with urethane color and/or clear as the urethanes are MUCH more durable period.

Save your spray cans and rustoleum for the wheelbarrow, tiller, and lawn furniture.

Blocking kit is mandatory for smooth panels https://www.autobodytoolmart.com/p-11890-14601.aspx

Various grits of sand paper to get you up to final sanding before top color are 36 or 40, 80, and 180 psa rolls. http://www.autobodytoolmart.com/mirka-autokut-psa-sandpaper-rolls-p-12052.aspx

For stripping a hood and panels get a variable speed 8 in. side sander/polisher.
80 grit PSA is ok. Watch the heat and keep moving. DIYs are ok with a Great Neck from autozone. 80 bucks. For good quality makita or dewalt. I like Makita.

Buy a gallon setup of epoxy and a gallon setup urethane primer.

Mixing lids are 15 bucks a piece get one for each gal of primer.

That should get ya started.
