2.0 is just enough.Helpful hints for Slick Sand? Is a 2.0 tip large enough? How do you clean your gun between mixes? Assuming you can only mix enough for one gun full at a time?
It is basically sprayable bondo, think of how much time you have when you mix bondo. It is almost that fast.2.0 is just enough.
I clean the gun thoroughly between pots, this is thick stuff and dries fast.
Yes, only mix one full gun at a time, again it dries FAST
Also, Im just gonna add this. If this were my project I would do your heavy bodywork, and then swipe the entire panel top to bottom, side to side with filler and shape it all up with a quality block.
Whether its urethane, poly primer or filler, the entire panel will have some type of "filler" on it. I'd prefer to have actual filler IMO. That's just me though. Swipe the entire panel and then you aren't chasing shit constantly. One panel at a time. It doesn't take that long. After that is complete, one coat of epoxy and then shoot your poly.
At that point you will be able to block the poly once and maybe spot some stuff in and then final prime.
Plenty of ways to skin this cat, just gotta pick your path. You are on the right coarse for sure regardless of the path you take.
The other 3 cars are all filler and epoxy (2 have SPI high build 2k). This is my first time with poly primer.. I may end up going back to just filler and epoxy before this is done
I actually just watched the videos you are referring to last week. I spent a few weeks with Wray, the knowledge he has is next level for sure, but I do think he sometimes gets ahead of himself, but if I had that much knowledge I'm not sure if I would even know what to do with all of it. lol. He does bounce around a fair amount as well.I try not to send new guys to Wrays channel, as although he does have some useful info, he also does some things absolutely wrong. Someone green may not pick up on those things and thus also learns the wrong way to do things.
A fabricated motorcycle fender should have the ducktail at the bottom added before the crease was put in down through the center. Any crease or fold acts as a lock, and makes it near impossible to add any additional shape afterwards. Thus the extra shape needed on the sides to add the lower tail could not be put in effectively; the center crease should have been the absolute last thing put in and was not. So he painfully struggles through it and never once mentioned that the order should have been changed.
Welding a patch in the top of a fender right up next to the mounting flange (think hood opening) is going to cause shrinking along/adjacent to that flange. As one would expect, the weld area shrunk and formed a low spot at the top of the fender. He attempted to relieve this by hammering things upward. This introduces tension on the flange such that the extra metal now wants to accordion the flange as the metal is looking for somewhere to go. He notices this when the fender is turned over and hammer and dollies the flange flat again. Then his body sweep shows the low again up top, and this process goes back and forth a few times without any light bulb going off in his head......."Houston, we have a problem..." Yes, the weld shrunk the area and until you PLANISH the weld to add STRETCH you will never correctly fix that low.. He never once mentions this actual cause and effect. I would hope at his level he understands that welds shrink.
I always considered Wray a smart cookie but blunders such as these, gone unmentioned, are just teaching others the wrong way to do things and/or not being able to recognize the cause, effect, and proper corrective action. He does a beautiful job on showing metal finishing, but sadly still has a low area where the weld shrunk the panel when he's done. And full disclosure, my work is not perfect, my metal finishing is not up to his standard, and he'll probably forget more than I'll ever know. But I try to learn from my mistakes and will often use those as teaching moments to show others the how and why of what happens when things don't follow the correct process. I try to insure everyone knows cause-effect of weld shrinking/distortion and proper methods to correct. So if anyone needs training videos I normally point them to David Gardiner or Peter Tommasini. Both these gentlemen were trained properly using traditional metalshaping methods and they do a very good job of explaining the basics so you can understand, up to the most difficult.
