About this deal
TIP: While colour mixing and working sugru in your fingers, sugru will get warm and this makes it more sticky. A bristle brush works well, too, but air pressure will do a better job of blowing out loose foam and plastic particles. As you work, it’s easy to forget where the plastic handle ends on this particular heating iron; I found out the hard way.
Perhaps no one but you will notice the revamped dashboard at first glance since it will blend it perfectly with the well-kept state of the interior. Since Fiber-Flex is recommended for hard-to-weld plastics, it works great for this application due to its high adhesion properties when melted.
Open the can of Filler Prep and use the cotton swab to clean the melted Fiber-Flex weld and about an inch outward on either side of the weld.
To begin, shake the can for about a minute and then practice your spray pattern on a piece of cardboard. The more area you cover outside the repair, the more likely it will bubble under higher temperatures; this is due to not giving the filler enough of a depression to bite into. I chose gloss because its sheen is closest to the original finish of the E21 dash and it’s more of a pure black than the landau color.Shake the can for a minute and spray a light coat over just the areas of the dash that have undercoating.
