Good to get a bit of feedback on this.
I do not want a sticky waxy coating on the underside anywhere.
The epoxy mastic stuff, what’s the process for this. After blasting the shell it’ll need to be primed more or less immediately,. Does this stuff go over the top of the primer or chipguard and dry hard without any heat softening it?
Every days a school day and that
Pretty sure epoxy mastic isn't a primer from the spec sheetEpoxy mastic is primer....go for Jotun, 5L delivery for 50ish of eBay (the rust busters 121 or whatever it’s called is actually Jotun rebranded)
You will need to key bare smooth steel prior to application but should be ok after blasting? Use 40 grit paper to key it.
It can be sprayed, but unless you have the chassis on a spit I wouldn’t bother and would paint it with a brush. Spraying it is a bit of an art.
Couple of coats, then seam sealer and finally finish with underseal.
The upol underseal products are fantastic and cost effective.
I would have used upol on my m3 but I had to stay OEM for resale purposes.
