coating fail and near primer disaster averted
well, i was a little dismayed to discover sections of the rust paint coating have failed. I 100% followed all instructions, you can see here that its failed on the chassis section that had no rust - but it had been sanded back to bare metal, then cleaned and then treated with the phosphoric acid.
The coating has taken fine over the rusted sections, but failed on a few sections of ' clean' steel.
You can see by the photos that the chassis was sanded with 40 grit in both directions - it was very rough.
In other news, I've started on the sandblasted steel wheels - they will get painted tomorrow.
I also bought the spray guns ( one for the primer, and one for the raptor liner with a 3.5mm nozzle) and the primer, tint etc.
Should be spraying undercoat on the 26th, weather permitting.
The big ' near disaster' occured the other day when the paint shop sold me acrylic primer to go under the raptor liner. The raptor technical sheets dont say you cant use it - but they also dont say you can - but they recommend either an etch primer or a 2k epoxy.
Because I'm spraying in a garage I want to avoid the 2k paints.
So I decided to call the shop back and ask them some more questions , luckily I got a guy who really knew what he was talking about and he said 'thank god you called - raptor will peel off an acrylic undercoat"
Yikes - that would have been a nightmare!!
Anyway, they sent a driver over to pick up the acrylic primer and hand over 4l of a 1k etch primer, so no harm done at the end of the day.
ok, back to prepping for the paint job and refixing the paint fail on the chassis...
