Hi guys!

I started making mold for mudguard and I  have now couple of questions.

1. can i use hammerite appliance paint on my plug? Becouse I did it and now it looks little bit like orange skin. Can i sand it to get smoother finnish?
2. can I apply Polarshine T10 before waxing on plug and later on mold?

Thanks

Hi,

Mmm, it doesn't seem like anything wants to bond to the plastic - it could be a plastic that's really difficult to bond to like ABS or polypropylene - in which case you have a couple of options. Option one is that you key the surface really heavily with a coarse abrasive paper and then use epoxy resin to coat the part - epoxy will bond better than paint or polyester resin - this might give you a good enough bond to do your surface prep and then pull the mould. Option two, if you really can't bond to the plastic surface is to use this to your advantage and pull a quick mould straight off the plastic surface. You can then use the quick mould to make a fibreglass mudguard (with all the surface defects still there) but then repair the fibreglass mudguard and polish that up to the final finish before taking your proper, final mould off that fibreglass mudguard.

And can I use fiberglass laminate sheets for flanges instread of sign board or something like that.

Yes, that would be fine.

I hope this helps.
