Vinyl wrap.

Hi. Anyone tried, or know of, using vinyl wrap to surface finish a plug prior to making a mould from it ? If it works it seems like it could save a lot of time & elbow grease.

It might be affected adversely by the solvents in galssfibre resins - unless you use two pack epoxy maybe?

Best bet would be to contact the manufacturers.

I've done it using a black bin liner when making up a polyester resin / glass seat in an MDF mold.
It worked better than expected and given that I wasn't looking for a perfect surface finish was a reasonable way of working!

I'm in the print trade and and produce a lot of vinyl (not wraps) but my supplier does vinyl wrap for boats so I guess it will work - try Pyramid Display and search wrap in the catalogue - might give you some answers!
cheers

Thanks for your comments. I've just ordered some wrap to experiment(play!) with & I'll let you know what happens. Cheers, Pete

Issue could be the exotherm process as the resin cures, may generate enough heat to cause the vinyl wrap issue. Maybe an initial thin coat and mat then when nearly cured and cooler, add further layers

I had wondered about the heat but vinyl wrap is applied with quite high temperatures to get it to form and stay formed so hopefully it will be fine.
I was chatting with someone earlier and they said the way they do wing mirrors is to lay the vinyl over the top of a relatively hot dustbin and just drop the mirror in!!

As someone who works with vinyl and resins I can safely say it doesn't work! The chemicals in the resin and gel cause the vinyl to expand and crinkle as the adhesive also fails ruining the mould and possibly the buck too.

A cast vinyl is slightly better than a monomeric vinyl but both give the problem to varying degrees

Vinyl is so thin it shows up any lumps and bumps below it anyway. To take a mould you don't need high gloss unless you want to get a finished glossy gelcoat on the piece. Primer is ok. Finish the plug with Lesanol or other two pack type high build primer and finish it with 320 grit prior to adding release.
