For a garage exterior, should i stick with a brand name like Sandtex from Screwfix
or will some thing from ebay like http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=321028914626&var=510089891031&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en
do the job just as well?
There is quite a price difference & i'll be doing inside & out.
Will i regret the cheap paint in the long run?
