Wrinkle Paint

[Sirkid]

I'm looking for a bit of help with wrinkle paint. Is VHT the only brand to get or would any brand of wrinkle paint do? Is there anywhere you can go and physically buy it in person in Ireland? It seems a bit expensive to buy online. Most sites I've looked at are shipping from the UK and it ends up costing about €50 for a pretty small can. I'd also take any advice on the valve cover gasket kit if anyone has recommendations. Thanks
