The valve covers are that hard plastic material (like the LS1 intakes), and I have a client that wanted to fill the grooves on it before I powder coated them. From what I understand, bodo & glass resin will fail in the oven temps? Is there anything that will hold to the oven temps (350*)? Any help would be greatly appreciated. Thanks.
I agree about the poss non sticking issue. I use the All Metal and use the plastic bondo applicators and the dried stuff peels/breaks off when you bend it. There's 2 diff Lab Metals, make sure to get the high temp version. Let us know how it goes...
Good info guys i had a customer asking what he could fill a few small scrapes in with on a swingarm. I couldnt even tell him i said leave it alone the powder will cover alot of it since they were very small.
Lab-metal is suitable for metal, wood, glass, porcelain or hard plastic surfaces
Surface needs only to be clean and dry
Spreadable, paintable and sprayable
You can cover a lot with the KL primer if you smooth it out in between coats. The "deep stuff" will require the hight temp type of bondo. The All Metal is good to 600 degrees, not sure about the high temp Lab Metal.
I dont know how much of a space you are trying to fill, but I use JB weld on the LS intakes and have not had a problem yet. I offgass first to make sure nothing will come out of the substrait after the filler is applied, then fill, harden, sand, clean yet again, and shoot.

Sir, you do SICK work!
Thanks for the input on the filler. The covers have 1/4" deep by 1/4" wide grooves across the tops, length wise (I think there are 5 or 6 grooves). I do have a few spares to play with, so I may try both methods. I was thinking if I used something like the "Lab/All Metal" I would have to fill the grooves, as well as spreading it over the whole cover, to help with adhesion. Guess I'll find out sooner than later
Thanks again everyone. I'll post some pics of the carnage most likely to ensue,
I've used JB weld before and for me it shrunk the more I heated it! The All Metal doesn't shrink, but the JB weld will probably be better in this case cause it should stick to the plastic better.
In the past, when I've needed JB weld to stick to something questionable. I've drilled several small holes in area where the repair is to be made. When you spread the filler on, it goes in the holes and hardens. It sort of acts like the finger holes in bowling ball. Not sure if it will work for your application, but I thought it was worth passing on.
I would hit it with some kind of sanding or grinding disc before smearing any filler on it - but that's just me. The grinding marks would have to be shallow enough to cover with KL primer or you would have to make sure to filled them, but not past.
After 10 years in the body biz, I can't get myself to put any filler on any surface that isn't roughed-up first.
Putting powder on a surface that has any amount of gloss (chrome, gloss basecoat) gives me fits too.

Everytime I see those I can't get over the way they look. Awesome work dude. I don't know how much of a difference it will make but the grooves he wants to fill are a lot deeper than those mold spots. Hope fully it will dig into his sanding well enough that he'll have as good as luck as you.
