Brief Description:  Painting process - Primer

I have now begun the priming process and have finally chosen the paint, PPG Desoto EAP-12 and Desoprime 7502 (2-pack epoxy). Another builder and I (Peter Clark: thanks for your efforts Peter), are splitting the product as it is only for internal parts and only for non-quickbuild internal parts and panels.

The main reaon for the choice is the 'relatively' more environmentally friendly (read: doesn't kill you) system, and it is a reasonable level of solution relative to the wash primer used on the rest of the quick build kit. Although I looked at chromates, the backyard nature of application, disposal issues, secondary ingestion issues (i.e. kicked up from the floor after turned to dust) and carcingenic nature of the chromates caused me to go the non-chromate 2-pack route.

The actual process I am following is:
1. Clean with a solvent (using Acetone)
2. Mild chemical etch (5:1 watered down AlumiPrep-33 in Garden spray bottle) Could use scotchbrite if looking little 'old'.
3. Application of EAP-12 (Boegel) adhesion promotor. (Garden spray bottle)
4. Application of 3 part expoxy primer.

I also purchased some equipment from overseas (UK). This was purchased from Andy at SprayGunsDireck.co.uk. Thier prices are excellent and service is good, even including the shipping costs which are good value.

Equipment purchased was:
1. Iwata air fed mask cheaper than here in Oz by x3.
2. Sata Minijet 4 spray gun with 1.2 SR
3. Disposable paint cup system (50 small and 50 medium)
4. Disposable gloves and paint suits (x3)

I have already noticed that although the fumes are not significantly dangerous, they are not particularly perfumed..... The face mask has come in very handy.

I have finished a test part and completed the spraying of a bearing and have noticed I need more practice. I also believe I have some water/oil in the line causing some minor surface imperfections. I have ordered a 3 stage line filter and some disposable devilbiss filters as temp solution.
