6-2-2019 – Undercoating

Undercoating is done! Using u-pol Raptor Bedliner.  Day one: Taping and plugging holes: I needed to protect part of the rear frame rails for when I install the sub-frame connectors. There there were various screw holes where I either used cotton balls or ear plugs (for shooting). Then I used plastic painters drop cloths to protect the rest of the shell and I covered the floor and tools to protect from over spray. The stars finally aligned and no more excuses to delay any further…  The lighting isn’t the best and I will try to get better pics in a week once it is completely dried. There are a couple of small things I want to do while it is still on the rotisserie, but be winter it will no longer be on the rotisserie!  Loki – my Norwegian Elkhound enjoyed the day supervising. 

I sprayed two coats with an hour between.  Temp was about 70 and 60% humidity.  I had a couple of fans going and the garage door open a jar for good air flow.  I had 8 bottles and ended up using 5.  I would do about half and start the other with a new bottle rather than go until the bottle is out.  Less than an hour to spray, an hour flash and then less than an hour to spray second coat.  I then waited an hour or so and removed the plugs and tape along with the plastic.  Take your time and make sure you review that you have all plugs out.

05-26-2019 – Undercoating Progress

Yesterday I was able to practice applying u-pol Raptor bedliner (for undercoating) to a spare piece of sheet metal.  Today I masked the shell in preparation which I hope to apply sometime next week (weather permitting)…

Before pic – I had previously sanded, primed, and scuffed: 1st coat at 50 psi: 2nd coat an hour later: Test tape and ear plug (for screw holes) removed after 45 minutes – no problem: Test tape and ear plug removed after 1.5 hours – no problem!: When it came to masking, I started at the front: Then each side of the car: Finally the rear: and wheel wells: I still need to cover the floor and tools and then clean and plug the holes and tape where I don’t want it to be applied. I have no concerns after testing on cardboard and the spare sheet metal – just need to find the time and have the weather cooperate. The temp was around 70-75 at 60% humidity inside the garage when I tested – doesn’t get any better than that!
