I run a garage who amongst many repairs carry out some underbody and suspension restoration work. I'd love to see a video of a subframe or suspension arm restoration using your rust converter and em121 please. We're doing an R55 mini clubman next week and would love to spray it's subframe once it's been shot blasted but only have hvlp

Useful video - thanks. What's the relationship between Custom 421 and EM 121? Can/should you use one on top of the other? Also how would either/both of them perform if used on top of etch primer? This is for a car underbody. Thanks

Custom 421 is a pure epoxy primer ( needs top coating) EM121 is a epoxy mastic primer finish ( can be left un-coated). No need to use one over the other, 421 is most popular for body panels, 121 for underbody. Both perform fine over an etch primer as long as that primer is well stuck.

Great video. Thanks. Being a general hobbiest looking for new products to use on my classic minis when rebuilding. Can this be used spraying in a home garage with basic half mask and filters??

I use this quite a bit brilliant product just wondering on my next restoration would it be a good idea to use this across a polyester spray filler instead of a high build primer only thing is I would have to sand it exactly smooth before basecoat alot of epoxys don't really like sanding

Custom 421 is a very easy sand even at full cure, polyester spray fillers can typically give a very high build so I would suggest you’ll need to sand this thoroughly before coating with 421, otherwise you’ll sand through the 421. Would you not be better to use the 421 first and then apply the polyester over the top before applying another coat of 421. This way you would be sandwiching the polyester in between the 421

@@uklam102 Sorry I didn't explain myself very well that's excalty what I mean bare metal, 421,poly,421,base and clear I think the 421 would be a better foundation rather than a high build primer thanks I'm gonna try it that way on the next one

The 421 would definitely be better, you’ll really benefit from apply it to bare metal.
