What can I use for filler/sculpting?

I've seen a few guys building their own dashes to accomodate screens etc over the years. What is the best filler to use that can be painted, sanded, sculpted etc? I think I've seen liquid stuff being used as well as putty type stuff. Just looking for as smooth a finish as possible.

 

I was thinking plastic bumper repair filler but I wasn't sure if that would do the job or not.

 

Cheers

I use standard bumper filler. Problem is for a decent finish your get air bubbles in it while mixing, so after sanding your find lots of holes, but a coat or two with filler primer and a high grade paper sand ca bring it up as smooth as you want it.

 

I'd use a standard filler, and get the final smoothed finish with a decent primer.

Coolio, will give that a go.

 

I have plenty of bog standard filler, I also have a couple of tins of the fine putty scratch stuff for filling in the holes etc. With regards to the primer I take it you mean the yellow high build stuff? Might need to get a can of that.

 

Any ideas what would be best for bonding? I'm looking to bond fibreglass to perspex. It's very thin walled so thinking that filler might not be good enough.

Filler isn't really that good at sticking to smooth surfaces. If there is an etch it does hold but can start to peel away fairly easy.

 

I tent to scratch up an area and use fibreglass with some resin, but I wouldn't know for those materials if it would be reliable.

 

I've seen white high build primer, but Halfords typically do the yellow stuff. My headlight intake is full of the stuff ;)

 

Might be worth dropping mitchell a line, he is well clued up and may have covered that kind of thing previously. I'd def say go with standard filler. If its near the heater in the dash, don't forget to let it properly cure off, I'd say 2-3 days under the stairs. I have been in a situation before where it had dried but due to being in a cold environment still had some movement to cure. Once inside a dash and directly affected by heat the filler reduced in size and cracked. As you can imagine it took the paint with it.

 

Whatever you do TAKE PICS, always love a custom build :)
