A) Adhesion prep:
1. Rough up the foam, sand the surface, get holes in it (spiked roller, dance on it with golf shoes?)
Blow off the loose kruft (power wash, let dry?)
2. First layer, full strength Glidden Gripper, push into roughed-up surface with bondo scraper
(Let cure? or proceed with skinning?)
B) Structural skinning:
1. Prep canvas pre GG, (prewash, preshrink) cut w/ generous edge excess
2. Heavily coat foam, flats and edges / joints / corners and soak canvas (roller / brush / both?) in full strength GG
3. Lay down canvas, ensuring 100% saturation no bubbles and flatitude (? roller / scraper / brush / all?)
4. Do edges / joints / corners as you go, cutting angles, trimming overlap (no idea handwaving here) then saturating in full strength GG
5. (not drying time between coats? tack?)
Add as-little-diluted-as-possible GG initial coats, then full strength to the canvas until certain all weave is well filled in
6. Repeat full strength coats to build up / smooth surface (? drying time between?)
C. outermost finish / skin
(? maybe micro bubbles / fairing compound if super-smooth outside finish desired?)
paint, gel-coat, aluminum sheet, whatever outside
maybe luan, birch ply paneling, beaded hardboard whatever indoors
I am trying to figure out what I will do with this also...
I believe that after blowing the dust off I would add a step of 91% alcohol wash of surface before any adhesive (from what I have read...not tested any of this yet....working on my level table now)
