Tonight I sprayed tinted Upol Raptor Liner with the upol shultz gun that was included with the kit on the tub bottom and firewall. The raptor lining part of the process was pretty easy. I'm glad I took the time to tape/mask because it is messy, and it is very smelly, considerably worse than the epoxy primer and 2 part top coat I sprayed yesterday. I was a slightly concerned the colour was a little light when I first started spraying but it appears to be darkening up to the same as the freeborn red chip I gave the guy a Napa to scan. He made me a pint of the colour without the binders to tint the Raptor liner. I poured 62ml (4 ounces) into each bottle along with 250ml (1 cup) of hardener, that is all there is room for in each bottle. Time will tell if the liner is durable enough for this application, the reviews here on mud are good so I'm confident it will be good.
Prep/app steps:
-wire wheeled any rust spots or dirt or old sections of the firewall
-roughed everything with a red scotch bright pad
-cleaned with duplicolour wax remover pre paint surface cleaner
-seam sealed all underside seams and joints
-taped and masked
-sprayed ep-2c endura primer (not necessary but it has rust inhibiting zinc in it and is very tough once cured)
-sprayed ex-2c freebrorn red endura on the areas that didn't need Rapor Liner. This is very tough as well when is cures on to the ep-2c primer
-brushed Al's HNR on most of the tub bottom and firewall because Raptor Liner is not reported to have the best heat and noise reducing properties, and it is way cheaper than lizard skin
-these 3 previous application steps were done in 1 afternoon to aid in chemical bonding of the products.
-the next night I sprayed the Raptor Liner, see above for how I mixed it. I recall the endura paint has a 24 hr recoating window, and the HNR is quite rough so I believe the raptor liner should bond good.
-1 kit (4 bottles) was ample to cover the bottom and firewall of my cruiser including the tranny hump and both sides of the heat shield I made. I did not spray it on the inside of the outer rear fender sheet metal. My tub is now a 43 series so it is 14" longer than a 40.
I paid 190 CAD for the kit and gun, and $133 for the tint, both at Napa in Grande Prairie. I'm sure it could be had for a little cheaper but not much when shipping from the US to Canada, plus it would have taken weeks to get here. Time will tell if it is durable.
