Let me start by saying I spoke with Barry on the phone earlier this week and could not have been more impressed with the level of knowledge and the willingness to share as we spoke. With that being said even though I was taking down notes I failed to fully capture exactly what I might have been doing wrong so here goes.
I have just recently started painting some smaller objects and have noticed that I'm not getting great adhesion between my primer and basecoat. I am able to chip the basecoat off of the primer and with my fingernail chip more and more off.
If I remember Berry correctly I think i was screwing up the process so I'll outline it below.
I'm using all HOK products at the moment(don't hate I hadn't found SPI yet). I'm also applying with an airbrush but am able to get a wet coat through it.
After sanding the part to 600 grit.
1.I apply my KD3000 hybrid epoxy primer at a 4:1:1 ratio medium builder surfacer/sealer.
2. After an hour I wetsand any imperfections, wash with soap and water, and let air dry for 30 minutes or so.
3. Apply BC25 or BC26 basecoat depending on what midcoat requires(KBC)
4. Allow proper flash times
5. Clear
If I remember correctly I think Berry had mentioned a couple areas.
1. I wasn't applying a sealer before the basecoat so there wasn't a chemical bite happening
2. applying the kd3000 as a sealer but then wetsanding it and washing it was defeating its ability to do its job
3. setting the part out in the sun will help cure everything up faster.
I had been wetsanding because I was getting some dryspray when applying the primer. This was more my fault and ignorance in not slowing down enough. Think I still had rattlecan application on my brain.
I do have a small detail gun with a 1.2 tip that I could apply the sealer with if you guys think that it would be better then the airbrush.
The parts I'm spraying are small roughly 3-4" and about 1" in diameter. You can see what I mean about a detail gun being overkill.
Maybe something like an Iwata lph80 would do good.
